## Linguistic Note

The spelling litre is the one adopted by the International Bureau of Weights and Measures. Liter is the variant used in standard American English.

While $\mathsf{Pr} \infty \mathsf{fWiki}$ attempts in general to standardise on American English, the name of this unit is one place where a deliberate decision has been made to use the international spelling, in order to provide consistency with the British spelling of metre.
