About Cooking Conversions
Cooking conversions are uniquely complex because they bridge volume and weight measurements through ingredient-specific densities. A cup of flour weighs approximately 120 grams, while a cup of sugar weighs about 200 grams and a cup of honey about 340 grams — using a single volume-to-weight ratio for all ingredients would produce unusable recipe results. Professional bakers overwhelmingly prefer weight-based measurements for consistency, but most home recipes (especially American ones) use volume measures. Our converter includes density data for 60 common ingredients sourced from USDA databases, ensuring accurate conversions between cups, tablespoons, teaspoons, and grams for each specific ingredient.

When would I need to convert Ounces to Teaspoons?
Cooking conversions between volume and weight are essential when following recipes from different countries, scaling batch sizes for baking, and ensuring precision in pastry work where small measurement errors can significantly affect 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.
