What is a Milliliter and a Gallon (US)?
The milliliter (symbol mL or ml) is a metric unit of volume equal to one-thousandth of a liter (1/1000 L). It is also equivalent to exactly one cubic centimeter (1 cm³). The milliliter is widely used in scientific measurements, medicine, and cooking.
The US liquid gallon (symbol gal US) is a unit of volume in the United States customary units system. It is legally defined as 231 cubic inches, which is exactly equal to 3.785411784 liters. It is commonly used for measuring larger quantities of liquids, such as gasoline, milk, and paint.
Note: The Milliliter is part of the metric (SI) system, primarily used globally in science and trade. The Gallon (US) belongs to the imperial/US customary system.
History of the Milliliter and Gallon (US)
The milliliter derives directly from the liter, established in France in 1795. As the metric system gained international acceptance, prefixes like 'milli-' (meaning one-thousandth) were applied to base units to create smaller or larger units. The equivalence 1 mL = 1 cm³ is a fundamental relationship in the metric system.
The gallon has ancient roots, evolving from various Roman and medieval units. The US liquid gallon is based on the wine gallon, which was standardized in England during the reign of Queen Anne in 1707 as 231 cubic inches. This definition was adopted by the United States. It differs from the Imperial gallon used in the UK and Canada.
