Cubic Decimeter

What is a cubic decimeter?

A cubic decimeter is the volume of a cube one decimeter on a side, exactly equal to one liter (0.001 m³).

Origin of the cubic decimeter

Derived from the decimeter; in 1964 the CGPM defined the liter as exactly one cubic decimeter.

Where it is used

Common in chemistry and engineering as an exact synonym for the liter.

When and where it was developed

CGPM, 1964.

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.
