About this tool
Cups to Grams Converter handles the volume-and-weight conversions that recipes constantly mix. One cup of all-purpose flour weighs about 125 g, one cup of granulated sugar about 200 g, and one cup of butter about 227 g, because each ingredient has a different density. A flat mL-to-g conversion would silently apply the wrong density and break your bake. This tool keeps a curated table of grams-per-milliliter values for over 40 common cooking and baking ingredients (flours, sugars, dairy, fats, syrups, nuts, oats, salts, leaveners, grains, and more), normalizes your input to milliliters and grams internally, and converts in either direction. Volume units use exact definitions: 1 US cup = 236.5882365 mL, 1 metric cup = 250 mL (used in Australia and many modern recipe books), plus US and UK teaspoons, tablespoons, fluid ounces, and liters. Weight units cover grams, kilograms, ounces, and pounds. A quick reference card shows the chosen ingredient at the standard measuring sizes (1 tsp, 1 tbsp, 1/4 cup, 1/3 cup, 1/2 cup, 2/3 cup, 3/4 cup, 1 cup, 1 1/2 cups, 2 cups) so you can plan a recipe at a glance. A Custom density option lets bakers who weigh their own ingredients enter a measured g/mL and override the default, which is the most accurate route since flour weight varies with sifting, packing, brand, and humidity. Useful for following a metric recipe in the US, an American recipe in Europe, scaling a bake up or down without losing the ratios, or converting bulk pantry weights into recipe quantities. Everything runs locally in your browser; nothing is uploaded.
