Convert torque between newton-metres, pound-feet, pound-inches, ounce-inches and kilogram-force-metres — enter one value and read it in every unit at once.
A Twist by Any Name
Torque is a turning effort – a force applied at a distance from a pivot. Mechanics call it pound-feet, instrument makers ounce-inches, and the rest of the world newton-metres. They all measure the same twisting moment, just with different force and length units bundled together.
| Equivalent | Value |
|---|---|
| 1 lb-ft | 1.356 N-m = 12 lb-in |
| 1 N-m | 0.7376 lb-ft = 8.851 lb-in |
| 1 kgf-m | 9.807 N-m = 7.233 lb-ft |
| 1 lb-in | 0.113 N-m |
Frequently Asked Questions
Pound-feet vs pound-inches?
One pound-foot is twelve pound-inches. Small-fastener specs are often in lb-in and larger ones in lb-ft – mixing them up is a classic error.
Is torque the same as energy?
No, even though both come out in newton-metres. Torque is a twisting moment (force times lever arm); energy is force times distance moved. They are deliberately kept as separate units.
What is oz-in for?
Ounce-inches measure the small torques of electric motors, servos and instruments, where pound-feet would be awkwardly tiny numbers.
