Metric system problems

[RoeeVulcan]

Hi guys. I come from a team in Israel where we use the metric system. While working on a few engine and gear ratio math I noticed stall torque was in lb*in. I am used to work in N*m. This seemed weird since lb is weight and N is force. Obviously I can transform lb to kg and then multiply it by g but.. That dosn't sound right. Is there any other measurement refered to by lb? One to do with force maybe?

Also, does anyone have the engines table in metric?
