Torque Converter
Converts torque between metric and imperial units — the numbers you need when a manual specifies a tightening torque in one system and your wrench reads the other.

The formula
result = value × (from factor ÷ to factor)
Each torque unit is defined by its size relative to the newton metre, so converting between any two is a single multiplication.
Every torque unit
| Unit | Symbol | In one newton metre |
|---|---|---|
| newton metre | N·m | 1 |
| pound-foot | lb·ft | 0.73756215 |
| pound-inch | lb·in | 8.8507458 |
| kilogram-force metre | kgf·m | 0.10197162 |
Frequently Asked Questions
How many pound-feet is 100 Nm?
73.76 lb·ft. Going the other way, one pound-foot is 1.3558 Nm.
Is lb-ft the same as ft-lb?
For torque they are used interchangeably, though lb·ft is the more correct order. Strictly, ft·lb is a unit of energy and lb·ft is torque — dimensionally identical but physically different quantities.
What is the difference between torque and power?
Torque is twisting force; power is torque times rotational speed. An engine can make high torque at low RPM and still produce modest power.
