Where it is used

Standard for engine displacement, laboratory volumes and medical dosing (often written cc).

When and where it was developed

CGS system, 19th c.

US Customary (Liquid)

US Fluid Ounce

What is a us fluid ounce?

A US fluid ounce is 1/128 of a US gallon (29.5735 mL).

Origin of the us fluid ounce

Derived from the gallon subdivision; distinct from the slightly smaller UK fluid ounce.

Where it is used

Standard for US beverage and nutrition labeling.

When and where it was developed

English customary; US since 1824.
