About Flour & Scale

Flour & Scale is a set of free, weight-based calculators for the kitchen math that actually needs solving — baker's percentages, recipe scaling, pan conversions, and the dozens of small conversions that come up between the recipe and the oven. Everything here is built around weight and ratios rather than "a cup of this, a pinch of that," the way professional bakers actually think about a formula.

Part of a small family of calculator sites

Flour & Scale is built by the same person behind Hook & Gauge (crochet and knitting calculators), Feed & Speed (machining and manufacturing calculators), and Filament & Layer (3D printing calculators) — each one built around the same idea: a specific hobby or craft has its own math, and that math deserves a tool that actually gets it right, not a generic converter bolted on as an afterthought.

Found something wrong, or want a tool added?

These calculators are built on standard, commonly published reference data, and checked carefully before publishing — but if something looks off, or there's a calculator you wish existed, feedback is genuinely welcome and shapes what gets added next.
