About This Calculator
Convert between US kitchen volume units (teaspoons, tablespoons, cups, fluid ounces, pints, quarts, gallons, and millilitres) and baking weight units (grams, ounces, pounds). Factors are exact per NIST SP 811 and US customary culinary definitions.
How It Works
Select Volume for liquid measurements or Weight for dry/solid ingredients. Choose the source unit and target unit, then enter the amount to convert. All factors are exact — 1 cup is exactly 8 fluid ounces, and 1 US fluid ounce is exactly 1/128 of a US gallon (3.785411784 L).
The Formula
result = value × factor(from) ÷ factor(to), where each factor is the unit's exact equivalent in mL (volume) or grams (weight). 1 tsp = 4.92892… mL, 1 tbsp = 14.78676… mL, 1 cup = 236.5882… mL, 1 oz = 28.34952… g, 1 lb = 453.59237 g (exact).
Frequently Asked Questions
- How many tablespoons are in a cup?
