Converting Insulin Milliliters To Units

Proper and Correct way of Insulin unit calculations

While we are on the subject of converting units of insulin to milligrams, it is important to discuss a common source of confusion regarding insulin dosing, which is the relationship between milliliters and units.

Insulin products are listed in terms of a concentration, such as U100 or U500.

U40 stands for:

  • 40 Units of insulin per 1mL

U100 stands for:

  • 100 Units of insulin per 1mL

U500 stands for:

  • 500 Units of insulin per 1mL

So, if you have a U100 insulin product, and you need to inject 50 units, that would come out to 0.5 mL.

Similarly, if you have a U500 insulin product, and you need to inject 50 units, that would come out to 0.1 mL.

You can convert between units and mL for the most common type of insulin concentration, U100, below.

U100 Insulin to mL Converter

Type in units of U100 insulin to convert to mL:


Milliliters: 0

If you are using syringes to draw up and inject your insulin, it is vitally important to be sure you are using the correct ones to prevent dosing errors.

For example, you cannot use U100 syringes if you are utilizing a U500 insulin product.Drawing up half-way, to 0.5 mL, on a U100 syringe will equal a dose of 50 units of a U100 insulin. However, doing the same with a U500 product would yield 250 units!

Example #4: Formulas Commonly Used To Create Insulin Dose Recommendations

This example illustrates a method for calculating of your background/basal and bolus doses and estimated daily insulin dose when you need full insulin replacement. Bear in mind, this may be too much insulin if you are newly diagnosed or still making a lot of insulin on your own. And it may be too little if you are very resistant to the action of insulin. Talk to your provider about the best insulin dose for you as this is a general formula and may not meet your individual needs.

The initial calculation of the basal/background and bolus doses requires estimating your total daily insulin dose:

Insulin Resistance In Dogs

It should be taken into account that, sometimes, insulin resistance can occur. In these cases, the need for insulin may increase because the original dosage becomes insufficient. There are several causes that can lead to insulin resistance, including obesity, secondary diseases, drug interactions, etc. It indicates that the diabetes is still not controlled and, therefore, it is necessary to go to the veterinary clinic again.

Pharmaceutical & Insurance Companies

The âBig Threeâ pharmaceutical companies that produce 90% of the insulin available on the market are Eli Lilly, Novo Nordisk, and Sanofi Aventis. Insurance companies will determine how much you pay out of pocket, depending on your type of plan and what cost-sharing policies are in place.;

For instance, those with more comprehensive insurance plans are likely to spend less than those with high deductibles.;

How Much Does A Month Of Insulin Cost

Everyone has different insulin needs. There isnt a one size fits all approach to determining how much insulin you need. Those taking analog insulin take a background or basal dose once or twice a day. In contrast, those taking regular human insulin take it three to four times a day.

This cadence is the only insulin some people with type 2 diabetes need. But for type 1 diabetes, and some with type 2, additional insulin is needed at mealtime. Depending on which insulin you are using, it should be taken 10 to 30 minutes before your meal. The amount of insulin depends on what you plan to eat. For example, you might need 1-3 units per carbohydrate portion .

People with type 1 diabetes generally use two different types of insulin per day. They start with two injections per day and progress to three to four doses per day, according to the American Diabetes Association . People with type 2 diabetes might start with 0.5-0.8 units per kilogram of body weight per day and eventually take 1-2 units per kilogram of weight. For a person weighing 150 pounds, this would be 68 to 136 units per day. For a person weighing 175 pounds, this would be 80-160 units per day.

One vial of insulin contains 1000 units, and pens contain 300 units.

How many units of long acting insulin (Basaglar, Tresiba, Toujeo, Lantus, Levemir) should I take?

Insulin is a hormone made by the pancreas that allows the body to use sugar in the food that you consume for energy. Insulin regulates the blood sugar levels in the body. Type 1 diabetics do not produce insulin naturally and must take insulin when they eat to help their bodies properly process glucose. Some type 2 diabetics need insulin as well, especially as the condition progresses if diet and exercise do not help.

Of the 30.3 million people in the United States with diabetes, about 5% are type 1 diabetics and need insulin to survive.

In the United States, insulin prices are extremely high and are continuing to rise. In 2012, the average annual cost of insulin per patient was $2,864 per year. In 2016, the prices nearly doubled to $5,705 per year. The cost of one insulin vial varies depending on the type of insulin and how the patient pays for it.

In addition to insulin vial, diabetics also pay for glucose monitors, test strips, lancets, and other supplies. Even with insurance, the cost of insulin can cost more than what most can afford. Insulin can range anywhere from $25 per vial to $300 per vial. Some people may need up to six vials per month.

In addition to vials, diabetics can choose to use insulin pens, which are prefilled and easier to use and travel with. Insulin pens, however, can cost more than vials per month because they typically contain fewer units of insulin.

Calculating Insulin To Carb Ratio

So how do you figure this all out?

Again, this is not something you ought to attempt to do alone, but always discuss with your physician and diabetes educator.

However, a general starting place is often 2.8x body weight divided by your current daily dose.

For example, if a 160 pound person were taking 50 units of insulin daily: 2.8 x 160 / 50 = 9.

In other words, its estimated that 1 unit of insulin would cover 9 grams of carbohydrates.

Now again, remember this is an estimated starting point, from here, youd tweak as needed based on your blood sugar log, which you are diligently keeping right???

Intensive Insulin Therapy Requires:

With MDI, insulin glargine or detemir is used to provide basal insulin; and insulin aspart, glulisine or lispro provide bolus coverage.

With an insulin pump, insulin aspart, glulisine or lispro provide both basal and bolus insulin replacement.

Carbs might be whats converted into glucose in the bloodstream the fastest, but its not the only macronutrient that can impact your blood sugar.

If you eat large amounts of protein, youll most likely need to inject insulin to not see an increase in your blood sugar.

If you add large amounts of fat to your meal, youll most likely see a delayed release of the glucose into your bloodstream, which for many people means that they need to take two insulin doses rather than just one .

How Do Scientists Produce Insulin

Are you curious to know about the synthesis of insulin in industries? Yes! So let me explain the process in simple words.

  • First of all, scientists manufacture the gene of human insulin.
  • Then, scientists insert this gene in bacteria through plasmid. Now they are recombinant bacteria.
  • Then, these bacteria are put in large fermentation tanks.
  • Here, the bacteria will produce insulin using the gene.
  • Finally, scientists collect prepared insulin for human use.

How Is It Given

Insulin is given by injection because it cannot be taken orally – the stomach will break it down so that is is no longer effective in breaking down blood sugar.

Insulin should always be dosed using special insulin syringes marked with insulin units. Common insulin U-100 syringes can hold 100 units; there are also Lo-dose syringes, which are syringes that can hold a total of 30 units or 50 units.

The above picture shows the syringes themselves but they are so small that they can be hard to read, so often we flatten out the measurement on the side of the syringes, so that each syringe label looks something like the pictures below:

Lo-Dose insulin syringe for measuring up to 50 units Each mark is 1 unit apart. Insulin syringe for measuring up to 100 units Each mark is 2 units apart. Insulin syringe for measuring up to 100 units Each mark is 2 units apart. Even numbers are marked on the scale on the rightand odd numbers are marked on the scale on the left.

What Is Insulin To Carb Ratio

So what is the solution?

Something called an Insulin to Carb Ratio: the number of grams of carbohydrates covered by 1 unit of rapid acting insulin.;

This is different for different peoplethose who are more sensitive to insulin will have very high ratios a small amount of insulin will cover a lot of carbs. Whereas those who are more insulin resistant will have lower ratios the same amount of insulin will cover fewer carbs. So its important to know how many carbs a certain amount of insulin will cover for you.

In this example, we need to know how many carbs you ate Monday and establish a ratio based on that. So lets say you ate 30 grams of carbohydrates.

That would give us: 10 units for every 30 grams, therefore a 1:3 ratio. In other words, 1 unit of insulin for every 3 grams of carbs.

Now once you know this ratio, you can adapt/modify it for varying amounts of carbohydrates at meals. For example, if you ate 9 grams of carbohydrates, youd give yourself 3 units , if you ate 21 grams of carbs, 7 units and so on.

Now to complicate this even further, you may need to add a sliding scale to this.this accounts for an already elevated blood sugar that needs to be corrected.

For example, if your I:C ratio was as above, that would be the perfect amount of insulin to give if your blood sugar was already in range. However, if your blood sugar was high, say 325 , you need to do more to account for a high level.

How Much Is 1 Unit Of Insulin

Meal time bolus insulin calculation – ‘Sugarman’

Maybe a silly question, but how is one unit of insulin defined? I know it is 1/100 ml of U100 insulin, but back in the days with U40 and U60 insulin that was different, obviously. So how is one unit defined? is it in mol? and who made the decision on how much one unit is? is this historically explainable?Would be really curious if anyone had answers.

“Units” of pharmacologically active substances are/were historically defined using some sort of easily carried out assay. Doesn’t make any difference whether you are using U100 or U40. That just indicates the concentration of insulin.

According to Wikipedia, 1 Unit of insulin was originally defined as the amount that would bring about a reduction in BG of 2.5 mmol/L in a fasting rabbit. I should imagine that this was the easiest or probably only way that the early researchers in the 1920’s and 30’s could measure it.

This has now been redefined as 1 Unit = 0.0347 mg


U100= 100 units of insulin per milliliter of fluid in the vial. So 1 unit = one hundredth of a milliliter.

One unit of insulin is one unit no mater which kind, each insulin strength has has it’s own syringe. One Unit of U100 has the same amount of active ingredient as one unit of U40 or U60.

Clinically speaking, one unit of any insulin will lower a persons BG the same amount but everyone’s insulin sensitivity is diffrent…

Clear as mud……..

How about this answer to your question, just to stir up some dust?

In the 1980’s, a unit was less than 1 cent.

Insulin For Dogs With Diabetes

See files for Dogs

Most of us won’t think about our insulin levels until there is a problem with them. Insulin fulfills a fundamental function in human bodies, but is equally essential for dogs. Incorrect insulin levels can cause a range of symptoms, some of which can be difficult to observe in our dogs, especially at first. When a body cannot produce enough insulin or when the cells cannot process it properly, diabetes occurs. This is a relatively common disease in dogs, but is fortunately treated with the administration of supplementary insulin.

In this AnimalWised article, we examine insulin for dogs with diabetes and help you understand the different types of canine diabetes medication. We also investigate the dosage and price of insulin for dogs.

  • How much does insulin for dogs cost?
  • How Much Insulin Should I Take: Correction

    If your blood sugar is too high during a period of fasting , you can calculate how much of the blood sugar needs to be lowered.;

    To figure this out, youll need to know your correction factor, also known as the insulin sensitivity factor.

    The correction factor is the amount of blood sugar that will be lowered by 1 unit of rapid-acting insulin.;

    This should also be figured out together with your healthcare team, using trial-and-error. Meanwhile, a helpful standard formula is the 100 rule or the 1800 rule.

    Blood sugar is measured in either mmol/L or mg/dL. The 100 rule is for people who use mmol/L, while the 1800 rule is for those who use mg/dL.

    These rules are formulas that involve dividing 100 or 1800 by your total daily dose. Thus: 100÷ total daily dose = the number of mmol/L of blood sugar dropped by 1 unit of rapid-acting insulin.;

    Alternatively: 1800 ÷ total daily dose = the number of mg/dL of blood sugar dropped by 1 unit of rapid-acting insulin.

    Lets say again that your total daily dose is 50, giving you the following calculation: 100 ÷ 50 = 2. This means that 1 unit of insulin lowers 2 mmol/L of blood sugar.

    Alternatively, the example could be the following calculation: 1800 ÷ 50 = 36. Accordingly, 1 unit of insulin lowers 36 mg/dL of blood sugar.

    Why Am I Paying So Much More Than $130 Per Year For My Insulin

    Right now, there is no competitive biosimilar insulin market. Not just in the United States anywhere in the world. This study sites the insulin oligopoly, regulatory challenges and regular incremental developments in insulin as three reasons we havent seen the emergence of a healthy biosimilar market. In order for the low prices suggested here to become a reality, multiple new manufacturing competitors need to enter the ring.

    Not only are the big three insulin manufacturers financially opposed to biosimilars entering the market, theyve actively taken legal steps to prevent it. In July 2017, Merck received FDA approval for Lusduna Nexvue, a biosimilar of Lantus. It has not launched in the United States because of an outstanding lawsuit Sanofi, maker of Lantus, sued Merck for patent infringement. Just this month, Merck announced that Lusduna will not come to market because of the cost associated with getting it there.

    The answer to why youre paying so much for insulin depends on where you live, what kind of insurance you have, and a slew of other variables. The studys authors remind us: final prices to patients or health systems may include additional mark-ups added during the supply chain. These mark-ups will vary between countries, as they may be subject to local negotiations, regulations, and other factors. In some cases, these additional markups can be very large.
