Hi Dear Friends,

I am reading a very old paper. And in this paper there is the following notation:

... internal dimensions 2 1/4 X 2 1/4 X 5 in.

My question is this: What means 2 1/4 ???

Thanks.

Valdemir.

Hi,
2 1/4 = 2 + 1/4

Valdemir,

unfortunately, the ominous inch is still heavily used as measure for length in the US, not only in "very old" papers. You should see how students here are struggling with that British "system", as they are required to know the SI as well.
