Why these converters?

British baking sits at a crossroads of three measurement worlds. Our classic cookbooks — Mary Berry's included — were written in Gas Mark and imperial ounces. Modern ovens are marked in Celsius, and half the recipes we find online now arrive from America in cups and Fahrenheit. A good conversion, done properly, is the difference between a cake that rises and one that sinks.

Each tool here is built for exactly the recipes on this site: the temperature converter knows the fan-oven rule, the cups converter weighs every ingredient separately (a cup of flour and a cup of sugar are very different things), the ounces converter speaks the language of classic British cookbooks, and the tin converter rescales a recipe when your tin is not the size the recipe expects.
