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.
