The story of the word

The French Academy chose mètre in 1791 for a unit defined as one ten-millionth of the distance from the equator to the North Pole, measured along the meridian through Paris. The survey was slightly off, so the original metre was about a fifth of a millimetre short. Poetic metre is the same Greek noun arriving centuries earlier by way of Latin, and the two senses have never merged.
