Peptide Calculator
Laboratory calculation tool
Concentration, solution volume, dilution and unit-conversion mathematics for laboratory work. Enter your values, press calculate, and the formula used is shown beneath every result.
Concentration after reconstitution
Enter the amount of lyophilised material in the vial and the volume of diluent added. Returns the resulting concentration and the equivalent volume for a chosen amount of material.
Dilution (C₁V₁ = C₂V₂)
Calculate how much stock solution and diluent are needed to prepare a working solution at a lower concentration.
Volume and unit conversions
Live conversions between millilitres, U-100 syringe units and mass units. A U-100 insulin syringe is graduated so that 100 units correspond to 1 mL, i.e. 1 unit = 0.01 mL.
Result
- 0.25 mL in U-100 units
- 25 units
- 25 units in mL
- 0.25 mL
- 1 mg in mcg
- 1,000 mcg
- 1 mg in µg/ng
- 1,000 µg / 1,000,000 ng
Formula: units = mL × 100; mL = units ÷ 100; mcg = mg × 1000; ng = mg × 1 000 000

Results are arithmetic outputs of the numbers you enter and must be checked by a qualified person against your own laboratory records and procedures.
