Glossary

Milliliter (ml)

A milliliter is one thousandth of a liter and exactly one cubic centimeter (1 ml = 1 cm³ = 0.001 L). It is the everyday metric unit for medication doses, beverage cans, cooking ingredients and lab work. A typical wine glass holds 175 ml; a standard espresso shot is about 30 ml; a 0.5 L water bottle is 500 ml.

US fluid ounce (fl oz)

A US fluid ounce is exactly 1/128 of a US gallon, or about 29.5735 ml. It is the dominant volume unit on US food, drink and personal-care packaging. Eight US fluid ounces make one US cup; 16 make a US pint; 32 make a quart; 128 make a US gallon. Do not confuse with the UK fluid ounce (≈28.41 ml).

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.
