From the Guidelines
For standard U-100 insulin, 10 units corresponds to 0.1 mL. The amount of insulin in milliliters (mL) corresponding to 10 units depends on the concentration of the insulin preparation being used. For standard U-100 insulin, which contains 100 units per milliliter, 10 units would equal 0.1 mL, as calculated by dividing the number of units by the concentration (10 units ÷ 100 units/mL = 0.1 mL) 1. However, it's essential to consider that insulin also comes in other concentrations such as U-40, U-200, U-300, and U-500. Some key points to consider include:
- With U-40 insulin, 10 units would equal 0.25 mL
- With U-200, it would be 0.05 mL
- With U-300, it would be approximately 0.033 mL
- With U-500, it would be 0.02 mL Most insulin used in many countries is U-100, so 0.1 mL is the most common volume for 10 units, but it is crucial to verify the concentration of your specific insulin preparation to ensure accurate dosing 1.

The volume in milliliters (mL) that corresponds to 10 units of insulin is calculated as follows:
From the Research
Insulin Concentration
- The common insulin concentration in most preparations of insulin is 100 units per mL or U-100 3.
- This concentration is the standard for most insulin preparations.
Volume of 10 Units of Insulin
- Given the standard concentration of 100 units per mL, 10 units of insulin would correspond to 0.1 mL (10 units / 100 units per mL) 3.
- This calculation is based on the standard U-100 insulin concentration.
