- 1Enter the Value to Convert.
- 2Choose the From and To units — Volume, Weight, or Temperature.
- 3If converting between Volume and Weight, also choose an Ingredient, since this conversion needs its density.
- 4Read the Converted Result below, in the target unit.
The Cooking Converter converts a value between common kitchen units across three categories: volume (teaspoons, tablespoons, fluid ounces, cups, milliliters, liters), weight (grams, kilograms, ounces, pounds), and temperature (Celsius, Fahrenheit). Converting within the same category (volume-to-volume or weight-to-weight) is exact and unit-based. Converting between volume and weight is only possible with an ingredient selected, because a cup and a gram measure different things and need a density (grams per cup) to bridge them.
Every unit has a fixed factor to a base unit (milliliters for volume, grams for weight).
Result = (Value × From-Unit Factor) ÷ To-Unit FactorUses a formula instead of a unit factor.

grams = (Value × From-Unit mL factor) × (Ingredient g/cup ÷ 236.588); the reverse divides instead of multipliesNot every pair of units can be converted.
Temperature ↔ Volume or Temperature ↔ Weight returns no result1 cup = 236.588 mL. Flour density ≈ 120 g/cup, so grams/mL ≈ 0.5072. Grams = 236.588 × 0.50723 tsp × 4.92892 mL/tsp = 14.78676 mL; ÷ 14.7868 mL/tbsp1 lb × 453.592 g/lb = 453.592 g; ÷ 28.3495 g/oz°F = (180 × 9/5) + 32 = 324 + 32- Volume and weight each convert directly using fixed unit factors (for example 1 cup = 236.588 mL, 1 lb = 453.592 g). Temperature uses its own formula instead of a factor.
- Converting between volume and weight (for example cups to grams) requires selecting an ingredient, because the two units aren't comparable without knowing the ingredient's density.
- Ingredient densities are approximate reference values (for example 1 cup of all-purpose flour ≈ 120 g); real-world density varies with how an ingredient is packed, scooped, or sifted.
- Converting between a temperature unit and a volume or weight unit is not supported and returns no result.
- The ingredient selector only appears when it's actually needed — when From and To are different categories and neither one is a temperature.
Are cooking conversions exact?
Volume, weight, and temperature conversions use fixed, precise constants (like 1 cup = 236.588 mL). Volume-to-weight conversions instead use an approximate ingredient density, so those results are estimates.
Why do I need to pick an ingredient for some conversions?
Only when converting between volume and weight (for example cups to grams). A cup and a gram aren't the same kind of quantity, so the calculator needs the ingredient's density to bridge them.
Why can converted measurements differ from what I measure with cups and spoons?
Real ingredients pack differently depending on how they're scooped, sifted, or leveled. The built-in densities (like 120 g per cup of flour) are reference averages, not a measurement of your exact ingredient.
Can I convert between temperature and volume or weight?
No. Temperature is not compatible with volume or weight units in this calculator, and that combination returns no result.
How is Celsius converted to Fahrenheit?
°F = (°C × 9/5) + 32, and the reverse is °C = (°F − 32) × 5/9.
