Hey guys, got a test result back and they gave it in lbs/in and I need it in N/mm as the requirement states. This is a breaking strength test for fabrics. I'm having a little trouble converting this, could anyone help me out? It is 88lbs/in

Wikipedia should have something comprehensive for this.  I have a handy conversion program that I will post here when I find it.

BTW, units are never pluralized; e.g., 'lbs' is a no-no.

My conversion program shows 1 lbf = 4.448222 N.

And 1 in = 25.4 mm.

Using unit cancellation from lb/in to N/mm gives you a factor of 4.448222/25.4 or 0.1751268

I use this conversion freeware program:
