Which is 0.8 pitch? is that closer to 48 or to 32?

0.8 module metric is closer to 32 pitch. In fact, it translates to something like 31.8 pitch.

Here's the conversion formula, in case anyone is wondering.

D = Diametrical pitch (ie 32, 48 or 64 pitch)
M = Module (ie 0.8, 0.6, 0.4)

M = 25.4/D
or
D = 25.4/M
