Solution Dilution Calculator (C1V1 = C2V2)

Calculate stock volume or final concentration for simple dilutions. Units must be consistent (e.g. % with %, mol/L with mol/L).

C1 (stock concentration)
V1 (stock volume) — leave blank to solve
C2 (final concentration)
V2 (final volume) — leave blank to solve

Formula

C1 × V1 = C2 × V2. Leave exactly one of V1 or V2 empty (or C2) to solve. Not for multi-component activity coefficients or non-ideal mixing volume changes.
