Dilution Calculator
Enter exactly three positive finite values and leave one field blank. C₁ and C₂ must use the same concentration basis and unit; V₁ and V₂ must use the same volume unit.
Enter exactly three positive finite values and leave one field blank. C₁ and C₂ must use the same concentration basis and unit; V₁ and V₂ must use the same volume unit. This is the four-variable arithmetic relation C₁V₁ = C₂V₂. It does not convert units, infer volume from mass fractions, or account for density, reaction, evaporation or mixing losses. It gives no mixing instructions. Results display at most 8 significant digits; the unknown input stays blank.

A QUICK WALKTHROUGH
How to use this tool
- Enter three known values.
- Leave exactly one value blank.
- Calculate the missing value in the results. The unknown field stays blank, so you can edit known inputs and recalculate.
