The working
concentration = powder ÷ water
— mg ÷ — mL = —
volume = dose ÷ concentration
— mg ÷ — mg/mL = —
units = volume × 100 (U-100 syringe)
— mL × 100 = —
This is a calculator, not a dosing instruction or medical advice. It only does arithmetic on the numbers you enter and can be wrong. Check every figure against your product before you draw or inject anything. Check with a doctor before making any medical decision.
How the maths works
Three steps of arithmetic, the same three the calculator shows you. It works on the numbers you give it and nothing else.
- 1ConcentrationThe powder in the vial divided by the water you add. 10 mg in 2 mL is 5 mg in every millilitre.
- 2VolumeYour dose divided by that concentration. 1 mg at 5 mg/mL is 0.2 mL.
- 3UnitsAn insulin syringe is marked in units, and on a U-100 syringe 1 mL is 100 units. 0.2 mL is 20 units.
