Cooking Measurement Converter
Convert between weight (grams, ounces, pounds) and volume (cups, tablespoons, teaspoons, milliliters) for common cooking and baking ingredients. Because a cup of flour and a cup of honey weigh very differently, this converter uses each ingredient's density for accurate results.
Why the ingredient matters
Volume-to-weight conversions depend on density. One US cup of water is about 237 g, but a cup of all-purpose flour is only ~125 g and a cup of honey is ~340 g. Pick your ingredient so the conversion reflects the real weight.
Common baking weights (per US cup)
All-purpose flour ≈ 125 g · granulated sugar ≈ 200 g · packed brown sugar ≈ 220 g · butter ≈ 227 g · powdered sugar ≈ 120 g · cocoa powder ≈ 100 g. Weighing ingredients is more accurate and repeatable than measuring by volume.
US cup vs metric cup
This tool uses the US customary cup (236.6 ml), tablespoon (14.79 ml), and teaspoon (4.93 ml). A metric cup is 250 ml and an Australian tablespoon is 20 ml, so recipes from other regions may differ slightly.
Frequently asked questions
How many grams are in a cup of flour?
About 125 g of all-purpose flour per US cup. Bread flour is a little denser at roughly 130 g.
Is a cup of sugar the same weight as a cup of flour?
No. A cup of granulated sugar is about 200 g while a cup of all-purpose flour is about 125 g, because sugar is denser.
Why do I have to choose an ingredient?
Converting between weight and volume depends on density, which differs by ingredient. Choosing the ingredient makes the result accurate.
Can I convert teaspoons to grams?
Yes — set teaspoons as the 'from' unit and grams as the 'to' unit, then pick your ingredient.
