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.

Attoliter (symbol: aL) is a metric unit of volume equal to one quintillionth (10^-18) of a liter. One attoliter is exactly equal to 1 × 10^-21 cubic meter, 0.001 femtoliter, or 1,000 zeptoliters. The attoliter is used to express extremely small liquid volumes encountered in nanotechnology, molecular biology, analytical chemistry, and microfluidics, where measurements often involve individual cells, nanoparticles, and microscopic droplets. Its relationship to femtoliters and zeptoliters makes it useful for scientific calculations and precise volume conversions at the atomic and molecular scale.

Ronnaliter (symbol: RL) is a metric unit of volume equal to 10²⁷ liters, or one octillion liters. The ronnaliter was introduced in 2022 as part of the expanded SI prefix system to represent extraordinarily large volumes. Although it has few practical applications today, it provides a standardized way to express immense quantities of liquids or gases in scientific research, astronomy, environmental studies, and large-scale data modeling. One ronnaliter is equal to 0.001 quettaliter or 1,000 yottaliters, making it useful for conversions involving the largest metric volume units.
