About Kitchen Index

Kitchen Index is an English-language reference for home cooks working from recipes written in different measuring systems. Start with a quantity you already know and find the amount you can measure in your own kitchen.

How the kitchen tools work

Each calculator explains its units and assumptions. Our ingredient index uses a separate weight for each ingredient. A cup of flour, for example, weighs much less than a cup of butter. Where your recipe gives a weight, use that weight first.

The recipe scaler multiplies ingredient amounts by the ratio of the two serving counts. The pan converter compares the area of the pans. Oven settings and cooking times still depend on your recipe and equipment.
