k means 1000 to a lot of the worldHello Lawrence,
k is a widely misused character.
k = karat, k=kelvin unit, k= km short for kilogram, running 2k= WHAT, k is for kinder garden
M = 1000, MM= 1,000,000 or better yet replace k
Hopefully, the correct term will become as widely accepted.
And as ad nauseam as it is, MM=2,000, not 1,000,000. The largest quantity represented by a Roman numeral is M (1,000). Multiples of a number are represented by a letter with a horizontal line over the letter. Hence 1,000,000 (1,000 times 1,000) is writtenM=1000 and MM=1,000,000.
