Tank Mixing Calculator
Calculate nominal stock and diluent volumes from final volume and matching concentration units.
A QUICK WALKTHROUGH
How to use this tool
- Enter positive final volume in litres.
- Choose a common concentration unit and enter stock and target concentrations.
- Calculate volumes and dilution factor, then copy or download the report.
Formula and units
Stock L = target concentration × final L ÷ stock concentration. Diluent L = final L − stock L. Dilution factor = stock concentration ÷ target concentration; undefined for zero target.
Scope
Use the same mass/volume units (mg/L or g/L), or ideal%v/v for both concentrations. Nominal volumes are assumed additive with no reaction. No w/w-to-volume conversion, density correction, compatibility judgment or safe mixing procedure is provided.
Local processing
Inputs stay in your browser. The report includes inputs, formulas and scope.
GOOD TO KNOW
Common questions
Can I enter weight percentages?
No. This volume model accepts matched mass/volume concentrations or ideal volume percentages only. Weight fractions require information outside this tool.
