About Mixing Ratio Calculator

A mixing ratio a : b means the mixture is divided into a + b equal parts, a of them component A and b component B. Each part is the total volume divided by a + b.

Formula

Mixing ratio

volume A = total × a/(a+b), volume B = total × b/(a+b)

Worked example

With the default values below, Mixing Ratio Calculator returns Volume of component A of 6.000000. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 6 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

10 litres mixed 3 : 2?

Five parts of 2 litres each, so 6 litres of A and 4 litres of B.

Is this the same as a dilution ratio?

Not always. A dilution written 1 : 10 usually means one part concentrate to ten parts diluent, giving eleven parts in total.
