Which tool do I need?

Every tool below is free, works on a phone, and asks what you are measuring before it converts, because a cup of flour and a cup of sugar do not weigh the same. Here is what each one is for.

Measuring and converting

• Grams to Cups Converter: pick an ingredient, enter grams, and get cups, tablespoons and teaspoons. It works the other way too.
• Ingredient Weight Chart: one cup of common baking ingredients, in grams, in one table you can print.
• Cups to Tablespoons: cups, tablespoons and teaspoons for small amounts and fractions like 1/3 cup.
• Cups to Ounces Converter: fluid ounces and weight ounces, which are not the same thing for most ingredients.
• Cups to Milliliters: US cups, metric cups and milliliters for recipes from other countries.
• Grams to Ounces: straight weight conversion for scales that only show one unit.
• Butter Converter: sticks, cups, tablespoons and grams of butter.
• Kitchen Conversion Calculator: quarts, pints, gallons and the other larger kitchen measures.

Ovens and pans

• Oven Temperature Conversion: Fahrenheit, Celsius, gas mark and fan-oven settings side by side.
• Cake Pan Converter: compares pan sizes so you know whether to scale the batter when you swap pans.
• Baking Time Calculator: a starting bake time when the pan, depth or size changes.

Scaling and planning

• Recipe Converter: halve, double or scale a whole recipe in one go.
• Cake Serving Size Chart: how many people a cake of each size and shape feeds.
• Frosting Calculator: how much frosting to make for a cake, cupcakes or a sheet cake.
• Yeast Converter: swaps between active dry, instant and fresh yeast.

Swaps

• Baking Substitutions: what to use when you run out of an ingredient, how much, and what the swap will change in the finished bake.
