What is a Cubic Meter?

The cubic meter is the actual SI unit of volume — the liter is only tolerated alongside it — and it takes over whenever a quantity is too big to picture in bottles. Water utilities bill in cubic meters, gas meters record them, and freight forwarders quote shipping space in them, because a cubic meter of cargo is a meaningful measure of what fits in a container. It is also the trade unit for bulk materials: concrete, topsoil and aggregate are ordered by the cubic meter, and the truck that delivers them is sized in them too.

What is an US Gallon?

The US gallon is defined as exactly 231 cubic inches, a figure inherited unchanged from the old English wine gallon. When Britain overhauled its measures in 1824 and adopted a new imperial gallon, the United States simply kept the wine gallon it already had — and that single decision is the root of the entire US-versus-imperial mess that still catches people out today. The US gallon is roughly a fifth smaller than the imperial one, which means American and British fuel-economy figures are not comparable even though both are quoted in miles per gallon.

To put both in perspective: a cubic meter is a cube one meter on every side, while a typical American milk jug holds one US gallon.
