What is a Fluid ounce and a Milliliter?
The fluid ounce is a unit of volume. The US fluid ounce is defined as 1/128 of a US gallon (approx. 29.57 ml). The Imperial fluid ounce is 1/160 of an Imperial gallon (approx. 28.41 ml).
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.
Note: The Fluid ounce is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Milliliter belongs to the metric (SI) system.
History of the Fluid ounce and Milliliter
Derived from the ounce unit of weight/mass, adapted to measure the volume of liquids like wine or water.
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.
Common Uses for fluid ounces and milliliters

- Science: Scientific notation for small volumes.
Frequently Asked Questions
Questions About Fluid ounce (fl oz)
Is a US fluid ounce the same as a UK fluid ounce?
No, the Imperial (UK) fluid ounce is slightly smaller than the US fluid ounce (approximately 28.41 ml vs 29.57 ml).
Is a fluid ounce the same as a weight ounce?
No, a fluid ounce measures volume (the space something occupies), while a weight ounce (specifically an avoirdupois ounce) measures mass (how much matter it contains). The relationship between the two depends entirely on the density of the substance being measured. For water, 1 US fluid ounce weighs approximately 1.04 avoirdupois ounces.
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).
Is mL or ml the correct symbol?
Both are technically correct and commonly understood. Similar to the liter (L/l), the capitalized version 'mL' is often preferred in publishing and medicine to avoid confusion between 'l' and the number '1'.
