Recipe Hydration Calculator
Find dough water from hydration percent.
How the Recipe Hydration Calculator works
Recipe Hydration Calculator turns flour grams and hydration percent into water grams. It computes that as flour weight times the hydration percentage.
Worked example: with Flour grams 500, Hydration percent 72, this tool returns water grams 360 g, flour grams 500, hydration 72 %. That default state is deterministic, so you can check the page against a known result before trusting your own numbers.
