[Milt -- N5IA]

And it probably has its origin in Latin.  I do know that "one thousand" in 
the Spanish language is "un mil" when speaking of quantities.  However, it 
is "Kilo" when speaking of weights and measures.  Strange.

de Milt, N5IA

1 mm = 1 millimeter = 1000th of a meter
1 mA = 1 milliampere = 1000th of an Ampere
1 mW = 1 milliwatt = 1000th of a Watt
1 mT = 1 millitesla = 1000th of a Tesla
1 mil (shorthand) = 1 milli-inch = 1000th of an inch

This "mil" has nothing to do with "million"

Unfortunately, one has to be cautious of common "technical slang" in an
international community.  Yes, common in US machinist's talk is for a
'mil' to equal 0.001 inch.  I am not certain of the origin and even
though I looked it up at Wikipedia, I still don't have any answer to why
'thou' is equal to 'mil' (even though I use and understand that unit
myself).
