maratoolHow to convert Nm to ft-lb for torque specs
Type a torque value — read N·m, ft·lb, in·lb, or kgf·m instantly.
Torque wrenches sold in the US read ft·lb, European service manuals spec N·m, and small fasteners use in·lb. The Torque Converter converts between all of them exactly.
How it works
- Pick units — "Newton-meter (N·m)" to "Foot-pound (ft·lbf)", or any other pair.
- Type a value — the result updates as you type, with swap and copy.
- Copy — one click, with "Copied!" feedback.
Torque conversion factors
Every unit converts through the newton-meter (the base unit). To convert A → B, multiply by A's factor and divide by B's:
| Unit | = this many newton-meters |
|---|---|
| Newton-meter (N·m) | 1 |
| Newton-centimeter (N·cm) | 0.01 |
| Foot-pound (ft·lbf) | 1.355817948331 |
| Inch-pound (in·lbf) | 0.112984829028 |
| Kilogram-force meter (kgf·m) | 9.80665 |
| Kilogram-force centimeter (kgf·cm) | 0.0980665 |
When you need it
The one to memorize: 1 ft·lbf = 1.3558 N·m, so a 100 N·m spec is about 74 ft·lb. Small-electronics screws are often specced in in·lb — divide ft·lb by 12, or just convert directly above.
Sources & methodology
Conversion factors follow NIST Special Publication 811; exact-by-definition factors are marked in the tool itself. All math runs client-side in your browser — nothing is uploaded.
