Volume is the measurement of the three-dimensional space occupied by a substance, object, or container. The SI derived unit of volume is the cubic meter (m³), while the liter (L)—defined as exactly 1 cubic decimeter (1 dm³ = 0.001 m³)—is the most widely used metric unit for measuring liquids. The milliliter (mL) is equal to exactly 1 cubic centimeter (1 cm³) and is commonly used for beverages, medicines, laboratory samples, and food products.

Different countries and industries use different volume units depending on local standards and applications. In addition to metric units such as the liter, milliliter, and cubic meter, the US and Imperial systems use units including the fluid ounce (fl oz), cup, pint, quart, and gallon. Since the US gallon (3.785411784 L) and the Imperial gallon (4.54609 L) are different units, accurate conversion is essential for cooking, engineering, manufacturing, scientific research, trade, and international product labeling.

US gallon (symbol: US gal) is a unit of volume used primarily in the United States. One US gallon is exactly equal to 3.785411784 liters, 0.003785411784 cubic meters, or 1/42 oil barrel. It is commonly used to measure fuels, beverages, chemicals, water, and other liquids in commercial and everyday applications.

Cubic decimeter (symbol: dm³) is a metric unit of volume equal to the volume of a cube with sides measuring one decimeter each. One cubic decimeter is exactly equal to 1 liter, 0.001 cubic meter, or 1,000 cubic centimeters. The cubic decimeter is commonly used in science, engineering, manufacturing, and education because of its exact equivalence to the liter. It is frequently converted to cubic meters, cubic centimeters, and liters for measuring liquids, container capacity, and solid volumes.
