Dilution Calculator for Cleaning Chemicals

Dilution Calculator

How much concentrate do you need to mix with water.

1. Dilution ratio

Dilution ratio is Water : Concentrate — For example... 40:1 means, 40 parts water to 1 part chemical. Pick a preset ratio or type your own (you can also type a single number, e.g. "40" for 40:1).

2. Amount of ready-to-use solution needed

Pick a preset or type an amount, then choose mL or L.

Enter a dilution ratio and an amount above to see your mix.
