Is it meter or metre?
Meter and metre are two spellings of the word that refers to a unit of measurement or the rhythmic structure of a poem (e.g., “The high jumper set a record of 2.45 meters/metres“). Meter is used in American English, and metre is used in British English. They are pronounced the same way.
