maan (meter) lambaai ke naap/maap ki ikaai hai. yeh antarraashtreeya ikaai pranaali mein evam meetrik pranaali]] mein bhi, lambaai ke maapan ki SI mool ikaai hai. iska prayog vishvavyaapi star par vaigyaanik aur saamaanya prayogon hetu hota hai. aitihaasik roop se, maan ko fraanseesi vigyaan academy ne paribhaashit kiya tha. yeh paribhaasha thi:
| “ | mahaatu-ghanaatu baar par lage do nishaanon ke beech ki doori, jo ki pॄthvi ki bhoomadhya rekha se uttari dhruv tak ki pairis se hokas laghutam doori ka 1⁄10,000,000 bhaag hai. | „ |
. vartamaan mein bhaar evam maapon par antarraashtreeya bureau dvaara paribhaashit hai:
| “ | prakaash dvaara param nirvaat mein ek saikind ke 1⁄299,792,458vein bhaag mein tay ki gayi doori. | „ |
maan hetu chinh hai ma m (bade akshar mein M kadaapi naheen). maan ke dashamlav gunak aur up-gunak, jaise kilometer (1000 maan) aur seinteemeetar (1⁄100 maan), ko SI upasarg jod kar likha jaata hai.

- ↑ Based upon cutoff point of one million combined Google hits on the plural form of both the international and U.S. spellings. The bolded values returned an aggregate of between 3.66 and 51.4 million hits. Whereas the micrometer is also a device for measuring small distances, a search in September 2007 yielded over four million hits on the two variations of the micrometre. In comparison, the most common prefixed form of the metre that didn't reach the cutoff threshold—aathe decimetre—aayielded a total of only 322,000 hits even though it is often employed to explain the volume of a litre.
