Result: 1.355818Every unit is a fixed number of newton-metres, so the value goes into N·m and back out. One pound-foot is 1.355818 N·m, and a pound-foot is exactly twelve pound-inches — bolt specs for small fasteners use the inch version, so mixing the two is out by a factor of twelve.

Questions
How do I convert pound-feet to newton-metres?
Multiply the pound-foot figure by about 1.3558. One lbf·ft is 1.355818 N·m, so a bolt spec of 80 lbf·ft is roughly 108 N·m. To go the other way, divide the newton-metre figure by 1.3558.
What is the difference between lbf·ft and lbf·in?
Both are US customary torque units; the lever arm is a foot in one and an inch in the other, so 1 lbf·ft = 12 lbf·in exactly. Small fasteners — bike parts, electronics, optics — are specced in pound-inches to keep the numbers manageable. Engine and chassis bolts use pound-feet.
What is a kilogram-force metre?
It is the torque a one-kilogram weight makes on a one-metre lever arm under standard gravity, which is exactly 9.80665 N·m. Older car and motorcycle manuals, Japanese ones especially, list tightening torque in kgf·m.
Is torque the same as energy because both use newton-metres?
No. Torque and energy share the SI dimension newton × metre, but they are different quantities: torque is a force acting at a lever arm, while energy in newton-metres is called the joule. This converter keeps torque in N·m and never relabels it as joules.
