The metric system uses liters (L) as the base unit for volume. 1 L = 1000 ml = 1000 cm³. For larger volumes, cubic meters (m³) are used, where 1 m³ = 1000 L.
The US uses gallons, quarts, pints, cups, and fluid ounces. 1 US gallon = 4 quarts = 8 pints = 16 cups = 128 fl oz ≈ 3.785 liters.
UK imperial gallons are larger than US gallons. 1 UK gallon ≈ 4.546 liters. UK fluid ounces are also slightly different from US fluid ounces.
For cooking: 1 tablespoon (tbsp) = 3 teaspoons (tsp). 1 US cup = 16 tablespoons = 48 teaspoons ≈ 237 ml. These are approximate conversions for everyday cooking.
