Understanding Volume Conversions

Volume conversions span metric units (milliliters, liters, cubic meters) and US/imperial units (teaspoons, cups, pints, quarts, gallons). The most important caution is that US and imperial gallons are different: a US gallon is about 3.785 liters, while an imperial (UK) gallon is about 4.546 liters.

For cooking, remember that a US cup is 236.6 ml and metric recipes often use a 250 ml cup, so quantities are close but not identical. One liter equals 1,000 cubic centimeters, which makes liters convenient for relating volume to mass for water (1 liter of water ≈ 1 kilogram).
