In machinist class we learned how to use a micrometer. We measured different engine parts and said stuff like 3 and 496 thousandths.
At lunch one bright fellow said, "Boy, them thousandths sure are small, I wonder how many there are in an inch?"

6 score and 5 eighteenths of a gross.[/b]

So that would be...

6x20 + 144x5/18 ?

That doesn't look right. There should be one thousand of those thousandths of an inch in an inch... even if that inch is imperial. Same goes with commoner inches and imperial decimals.

Okay, so 6 score and 5 eighteenths of a gross is 125/18 OF 144

144/(125/18)

And that would be what... about 20.7 thousandths of an inch in one thousandth of a meter? I think there should be almost twice that many. If I remember correctly there are almost 40 inches in a meter... 39.3?
