What is a Milliliter and a Gallon (UK)?
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 UK gallon (Imperial gallon) is a unit of volume defined as 4.54609 litres.
Note: The Milliliter is part of the metric (SI) system, primarily used globally in science and trade. The Gallon (UK) belongs to the imperial/US customary system.
History of the Milliliter and Gallon (UK)
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 Imperial gallon was defined based on the volume of 10 pounds of distilled water weighed in air with brass weights with the barometer standing at 30 inches of mercury and at a temperature of 62 °F.

Questions About Milliliter (mL)
Is a milliliter the same as a cubic centimeter (cc)?
Yes, 1 milliliter (mL) is exactly equal to 1 cubic centimeter (cm³ or cc). The terms are often used interchangeably, especially in medical and automotive contexts (e.g., engine displacement often uses cc).
How many milliliters are in a liter?
There are 1,000 milliliters (mL) in 1 liter (L).
