Dilution calculator: C₁V₁ = C₂V₂

Calculate a dilution concentration or volume from three known values using C₁V₁ = C₂V₂.

Enter exactly three values among C₁, V₁, C₂ and V₂. Leave the quantity you want to calculate empty.

Stock solution / before dilution
Diluted solution / after dilution

Assumption: the amount of the solute of interest is conserved between the aliquot and the final solution. Use the same concentration family on both sides.

A factor above 1 represents a dilution; a factor below 1 means the entered values describe concentration rather than dilution.
