Perfumery calculators

Two small tools for the bench, free and with no sign-up: work out a dilution, and turn a parts formula into percentages. Everything runs in your browser.

Dilution calculator

Decide how much aroma material and how much solvent (perfumer's alcohol, DPG, IPM) to weigh for a dilution at a target strength.

Aroma material1.000 g

Solvent9.000 g

Weight is the honest way to dilute. By volume, density differences shift the real strength a little; weigh if you can.

Parts to percent

Enter each material in parts (drops, grams, any unit, as long as it is the same one throughout). Get the percentage of the whole, the way a formula is written up.

Total parts0

Percentages are each material's parts divided by the total, times 100. They always add up to 100.
