Work out mixing ratio instantly with clear inputs, formula shown and shareable results.
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.
Mixing ratio
volume A = total × a/(a+b), volume B = total × b/(a+b)
Five parts of 2 litres each, so 6 litres of A and 4 litres of B.
Not always. A dilution written 1 : 10 usually means one part concentrate to ten parts diluent, giving eleven parts in total.
