FlourScaleWhy use baking calculators?
Baking is chemistry you can eat. Small differences — 20 g of extra flour from a packed cup, a 9-inch recipe squeezed into an 8-inch pan, instant yeast used like fresh yeast — change texture, rise and bake time. Each calculator here does one job well and explains the reasoning, so you understand the result instead of just trusting a number.
Accurate numbers from reputable sources
Ingredient weights come from the King Arthur Baking ingredient weight chart, with USDA FoodData Central values for liquids and fats. Yeast conversions follow King Arthur Baking's professional reference, oven conversions use the exact Fahrenheit–Celsius formula with the standard UK gas-mark scale, and dough calculations use the baker's percentage system used in professional bakeries. Every page shows a worked example so you can check the maths yourself.

Weigh when you can
If you only change one habit, make it weighing your ingredients. A basic digital kitchen scale removes most of the variation that causes failed bakes, makes recipes easy to scale, and means fewer measuring cups to wash. Our cups to grams converter helps you translate your favourite volume recipes to weights once, so they come out the same every time.
