Glossary

Liter (L)

A liter is the standard metric unit of volume, equal to 1 cubic decimeter (1 L = 1000 ml = 0.001 m³). It is used worldwide for beverages, fuel sold in metric markets, kitchen recipes and small-scale chemistry. One US gallon holds about 3.785 L; one UK imperial gallon holds about 4.546 L. The symbol is "L" or "l" (capital L preferred to avoid confusion with the digit 1).

UK (imperial) gallon

A UK imperial gallon is exactly 4.54609 L or 277.4194 cubic inches — about 20 % larger than the US gallon (3.785 L). Used in the United Kingdom and a few Caribbean countries for fuel economy figures (miles per UK gallon) and historical recipes. One UK imperial gallon equals 8 UK pints or 160 UK fluid ounces.

Metric / SI volume

In the metric system, volume is reported in liters (everyday) or cubic meters (industrial), with millilters for fine resolution. The relations are exact powers of ten: 1 m³ = 1,000 L = 1,000,000 ml, and 1 ml = 1 cm³. The metric system is the standard worldwide for science, beverages, fuel in metric countries, and most modern recipes outside the United States.

Imperial / US Customary volume

US customary and UK imperial systems both use gallon, quart, pint and fluid ounce — but with different sizes. The US gallon is 3.785 L (128 US fl oz); the UK imperial gallon is 4.546 L (160 UK fl oz). Cooking units (tsp = 4.93 ml, tbsp = 14.79 ml, cup = 240 ml) follow the US standard in nearly all modern English-language recipes.
