CALCULATION GUIDE

Understand your calculation

Clear inputs, a practical example and the context you need to interpret your result.

How it works

Percent v/v = solute volume ÷ final solution volume × 100, after conversion to mL.

Inputs and units

Enter nonnegative solute volume and positive final volume; solute volume must not exceed final volume in this simple model. Select uL, mL or L independently.

Worked example

25 mL ÷ 100 mL × 100 = 25.0000% v/v.

Interpreting the result

This describes 25 mL of liquid solute made up to 100 mL of final solution.

Assumptions and limitations

Do not assume that adding 75 mL solvent produces exactly 100 mL. Volume contraction, temperature and stock purity are not included.
