In practice
Foot-pounds to newton-metres multiplies by 1.35582, because one foot-pound of torque equals 1.35582 N·m. It is the conversion for torque wrenches, wheel nuts, engine specifications and bike components: a wheel nut torque of 80 ft-lb is 108 N·m, and a typical bike stem bolt of 5 N·m is 3.7 ft-lb. Over-tightening can strip threads or crack parts, so use the figure in the same unit as the wrench. Check the wrench scale carefully, since torque wrenches are often marked in both units.
