## this is a conversion

does this make sense to you guys?

forget the conversion from what to what. that's irrelevant. I'm don't understand where the 30,000 or the 1550 or 454 numbers come from. or how the units came about.

I got it from here: http://wiki.answers.com/Q/Can_you_convert_gsm_to_mil

thanks.

1 GSM = 0.0426 mil if the density is of Polyethylene or 0.92g density.

1 mil = 23.474 GSM

m2 (1) g 30,000 in2 mil lb (30,000)

_____ x _____ x ________ x ___ x ____ = MIL _________ = 0.0426

1550 in2 m2 lb 1 454g (1550 x 454)

Example 60 GSM = (60*30,000) / (1550*454) =2.56 mil

60 * .0426 = 2.56 mil

i don't get it either. I think this guy is just showing off.
after looking at it, you'll eventually realize it's just the density. I'm just trying to figure out the rest.
