About Cooking Conversions

Cooking conversions carry an extra step: volume and weight only connect through each ingredient's density. A cup of flour is about 120 grams, a cup of sugar about 200, a cup of honey about 340. Apply one volume-to-weight ratio to all three and the recipe fails. Professional bakers weigh their ingredients for exactly this reason, though most home recipes, American ones especially, still measure by the cup. The conversions below pull density data for 60 common ingredients from USDA databases, so cups, tablespoons, teaspoons, and grams line up for the specific thing you are measuring.

Cooking conversions between volume and weight come up when following recipes from different countries, scaling batch sizes for baking, and working in pastry, where a few grams off can ruin the result.

How precise are the conversions?

All conversions use exact factors verified against NIST and ISO standards with up to 10 significant figures of precision. Results are calculated using IEEE 754 double-precision arithmetic, which provides approximately 15-17 significant digits. For temperature and other non-linear conversions, exact formulas are used rather than approximations.
