Laboratory tool
Dilution calculator
Start from a solution that already has a concentration and make it weaker by adding diluent. Enter any three of the four quantities and the fourth is derived from them. Every figure is arithmetic on the values you supply — nothing is recommended, assumed, or suggested.
Leave exactly one field blank — it is derived from the other three. Dilution makes a solution weaker; a target concentration above the stock is concentration, not dilution.
