Dilution Calculator
Solve C1V1 = C2V2 for any unknown volume or concentration — a fast way to work out standard and sample dilutions for volumetric analysis.
Dilution calculations are a routine part of volumetric analysis — preparing stock solutions of standards, diluting samples to a target concentration range, or building a calibration series all come down to the same relationship: C1V1 = C2V2.
Pick which value you need to solve for (initial or final concentration, or initial or final volume), enter the other three, and the calculator returns the answer rounded to three significant figures, without trailing zeros on whole-number results.
