The French should be given full credit for inventing the unit of

Also, this avoids confusion with the frequently used word "METER", a
measuring instrument, when they are both mentioned in the same

I'm so glad to hear you're committed to correctness and against
confusion. Perhaps you can direct some of your efforts toward your
countrymen - the U.K. is the only place I've been where "m" is used as
an abbreviation for both metres and miles.
