THE KITCHEN TOOLKIT
Make room
for the cooking.
A few simple calculations, done carefully. These tools work in your browser.
01 / TEMPERATURE
Celsius ↔ Fahrenheit
This converts units only. It does not adjust for fan ovens or change a food-safety endpoint.
02 / DOUGH
Baker's hydration
Water ÷ flour × 100. Include flour and water from a starter. Milk, eggs and other ingredients need separate accounting.
03 / QUANTITIES
Scale an ingredient
Use the same unit before and after. Scaling ingredients does not automatically scale pan size, cooking time or leavener behavior.
Keep the numbers in context.
Use a recipe's own weights when available. Measuring cups are not interchangeable across all regions or ingredients.
