How does volume conversion work?
Volume conversion uses fixed ratios between units. This tool converts through liters as the base unit. All US customary units are based on the US fluid gallon (3.78541 L): 1 gallon = 4 quarts = 8 pints = 128 fluid ounces. Cooking measurements follow US standards: 1 cup = 8 fl oz = 236.588 mL, 1 tablespoon = 3 teaspoons = 14.787 mL.
Unit reference
Metric: milliliter (mL), liter (L), cubic meter (m³) — 1 L = 1,000 mL = 0.001 m³. US customary: teaspoon (tsp) = 4.93 mL, tablespoon (tbsp) = 14.79 mL, fluid ounce (fl oz) = 29.57 mL, cup = 236.59 mL, pint (pt) = 473.18 mL, gallon (gal) = 3,785.41 mL. Note: Imperial (UK) units differ from US — an Imperial gallon is 4.546 L vs the US 3.785 L. This tool uses US measures.
