Transparent math
Simple enough to follow.
Detailed enough to verify.
Every calculation converts compatible inputs to a common base unit before applying the formula. IU calculations remain separate from mass because IU-to-mass conversion depends on the substance. Results include equivalent mL and µL values so researchers can independently check the scale.

Stock concentration × stock volume = target concentration × final volume
Calculator guide
Laboratory solution math, explained plainly.
This free research calculator handles three common laboratory calculations without hiding the formula or unit conversion.
Solution concentration
Enter material amount and final solution volume. Mass results appear in mg/mL and µg/mL. IU inputs produce IU/mL; IU is never converted to mass.
concentration = mass ÷ final volumeLaboratory dilution
Enter stock concentration, target concentration, and final volume. The calculator returns the required stock and diluent volumes.
V₁ = C₂ × V₂ ÷ C₁Common calculation questions
How do I convert mg and µg?
One milligram equals 1,000 micrograms. The calculator normalizes both units before it applies the formula.
How do I convert mL and µL?
One milliliter equals 1,000 microliters. Results show both units when that makes the scale easier to verify.
What does C₁V₁ = C₂V₂ mean?
Stock concentration multiplied by stock volume equals target concentration multiplied by final volume. This relationship is used to calculate the stock volume needed for a laboratory dilution.
Does this calculator choose a research quantity?
No. It performs arithmetic only from values the researcher enters. It does not recommend quantities, protocols, dosing, administration, or injection.

Important boundary
For laboratory calculation and research planning only. Not medical advice. Not for human or animal use, dosing, administration, or injection. Calculations assume the entered liquid volume is the final solution volume and that dilution volumes are additive. Account for displacement or non-ideal mixing when your validated protocol requires it. Verify calculations independently and follow your laboratory’s procedures.
