a "Grand"?
At lunch one bright fellow said, "Boy, them thousandths sure are small, I wonder how many there are in an inch?"

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.

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?
Edit: 39.3701 inches = one meter
