About UnitChef

UnitChef exists because a cup of flour and a cup of sugar differ by 60 grams — and recipes pretend otherwise.

Volume measuring works for liquids and fails quietly for everything else: flour compacts, brown sugar packs, cocoa sifts, chopped nuts settle. The same "1 cup" spans a 20% weight range depending on technique — which is why two bakers can follow one recipe and bake two different cakes.

The database holds the standard weights — spooned-and-leveled cups, USDA-backed — for the ingredients that actually differ, with the density notes and substitution hints that make conversions safe.

We are cooks and educators, not a brand. Nothing here sells scales (but buy one), and the whole table works offline in your browser.

What makes UnitChef different

• Your numbers never leave your browser. Every calculator on UnitChef runs entirely on your device. We never see, store, or transmit the figures you enter — there are no accounts and no server-side processing of your inputs.
• Published methodology. Each calculator page explains the exact formula it uses and the assumptions behind it, so you can check our work or reproduce it in a spreadsheet.
• Free, forever, without a paywall. UnitChef is supported by advertising. There is no premium tier, no email gate, and no upsell.
