Dilution Calculator

Solve C1V1 = C2V2 for any unknown.

C₁V₁ = C₂V₂
Initial volume

Use any consistent units. Concentrations and volumes don’t care, as long as both C's use the same unit and both V's use the same unit.

About

Enter any three of: starting concentration, starting volume, target concentration, target volume. The tool solves for the fourth. Useful for chemistry labs, mixing solutions, diluting cleaners, brewing, or anything that needs precise concentration math.

How to use

  1. Enter three of the four variables.
  2. Read the fourth.

FAQ

Do units matter?+

Concentration and volume just need to be consistent on each side. The tool doesn't care what units you use as long as you use the same ones for both concentrations and both volumes.
