Not sure where to start?
Most people come for one of three things: converting cups to grams for a baking recipe, scaling a recipe up or down, or finding a substitute for an ingredient they ran out of. Start with the Cups to Grams Converter, the Recipe Scaler or the Butter to Oil Converter. If you want the numbers behind the tools, the Ingredient Density Lookup lists the 1-cup weight of 30 common ingredients with sources.
