Torque Converter
Convert N·m, kN·m, lbf·ft, lbf·in and kgf·m.
Quick answer
- Formula: Result = Value × (factor of from-unit in N·m) ÷ (factor of to-unit in N·m)
- Worked example — Converted torque: 73.756215 (full example below).
Torque Converter
| Converted torque | 73.756215 |
| Summary | 100 N·m = 73.756215 lbf·ft |
100 N·m is 73.76 lbf·ft — the setting on many torque wrenches sold in the US.
Convert torque (turning force) through the newton metre. The imperial workhorse, the pound-foot, is exactly 1.355817948 N·m; a pound-inch is one twelfth of that, and a kilogram-force metre is exactly 9.80665 N·m.
Context: a typical car wheel nut is torqued to about 100 N·m (74 lbf·ft), while engine outputs of 300 N·m are quoted as 221 lbf·ft in the US.

Frequently asked questions
How many N·m are in a foot-pound?
1.355818 N·m. To convert lbf·ft to N·m multiply by about 1.356; the reverse divides by it.
Is torque the same as energy since both use N·m?
The units match but the concepts differ: torque is a force acting at a distance (a vector), while the joule measures work done. Torque is never quoted in joules.
Why do small fasteners use lbf·in?
Small torques read better in pound-inches: 60 lbf·in is a clearer spec than 5 lbf·ft. There are exactly 12 lbf·in in 1 lbf·ft.
