About Volume Units:

Cubic Meter (m³):The standard unit of volume in the International System of Units, representing the volume of a cube with 1-meter sides. Commonly used to measure the volume of large objects, rooms, cargo, and more.

Liter (L) / Milliliter (mL):The most commonly used units of capacity in daily life. 1 liter equals 1 cubic decimeter, and 1 milliliter equals 1 cubic centimeter. Widely used for beverages, liquid medicines, cooking, and other scenarios.

Gallon (gallon):A common unit of capacity in the UK and US, but the US gallon and UK gallon differ in size. The US gallon is about 3.785 liters, while the UK gallon is about 4.546 liters. Be sure to distinguish between them when purchasing imported goods.

Cubic Foot (ft³):An imperial volume unit representing the volume of a cube with 1-foot sides. Commonly used in construction, lumber, concrete, and related industries.

Barrel (barrel):Mainly used in the oil industry, where 1 barrel of oil is approximately 159 liters. Barrels are also used in the beer industry, though capacity standards may vary.

Cooking Units:Common cooking volume units include cups, fluid ounces, tablespoons, teaspoons, etc. Standards may vary slightly across countries and regions, so pay attention to the unit system when following recipes.
