Reading a book from 1905, I came across the word “centim”.
From the context, this clearly meant “centimetre(s)”, but it was an alternative I had never encountered before.
This page provided some information.
I have never had much use for decimetres/decim. A decimetre is one hand, if you are interested in horses.
“Centimetre” and “millimetre” are relatively long and unwieldy words for terms that may be used frequently.
It is already common to use the word “kilo” rather than “kilogram”.
Why not bring centim and millim back into fashion? Millim is a palindrome, which may help me remember it is two “l”s.
While we are at it, let us adopt “megagram” (Mg) as an alternative to “metric tonne”.
And also, let us adopt the word “milliard” to cut through the whole billions/trillions confusion. Instead use milliard, thousand milliard, million milliard etc until exallion (10^18)
