What's inside
Built for the way bakers actually work.
01
FreeUnit Converter
13 baking units: tsp, tbsp, fl oz, cup, pint, quart, gallon, ml, litre, g, kg, oz and lb. Type fractions like 1/4 or 1 1/2, pin favourites, and choose US, metric or UK cups.
02
FreeIngredient Converter
Volume to weight for 126 ingredients, using densities benchmarked against King Arthur Baking. Missing one? Add your own with its density.
03
FreePaste a Recipe
Paste a recipe one ingredient per line and Crumbs converts every line to grams. Anything it isn't sure about is flagged so you can pick the right ingredient.
04
FreePan Size Converter
Round, square or rectangular, in cm or inches, with optional depth. Get the batter multiplier and a bake-time hint, then scale your recipe by it.
05
FreeReference Tables + Baker's %
Searchable tables for oven temperatures (°F, °C, Gas Mark), volume and weight, plus 23 baker's ratios. The Baker's % calculator handles yeast or levain and shows the levain build.
06
