Reading N·m torque specs on a ft·lb wrench
1 N·m is 0.7376 lbf·ft (pound-force foot) or 8.85 lbf·in. Service manuals give torque in N·m, while many US wrenches are scaled in lbf·ft for larger fasteners and lbf·in for small ones.
| N·m | lbf·ft | lbf·in |
|---|---|---|
| 10 N·m | 7.38 | 88.5 |
| 25 N·m | 18.44 | 221.3 |
| 50 N·m | 36.88 | 442.5 |
| 100 N·m | 73.76 | 885.1 |
| 120 N·m | 88.51 | 1,062.1 |
- Check which scale the wrench uses. A 10 N·m spec is 88.5 lbf·in but only 7.38 lbf·ft; setting 88 on the wrong scale tightens the bolt 12 times too hard.
- Click-type torque wrenches are commonly certified to within ±4% of the set value under ISO 6789. Rounding 88.51 lbf·ft to 89 changes the setting by 0.6%, far inside that tolerance.
- "ft-lb" and "lb-ft" on a spec sheet mean the same torque. Engineers often keep lbf·ft for torque and ft·lbf for energy, but the numbers are identical.
- This page converts units only. The tightening torque itself, and whether threads are dry or oiled, comes from the manufacturer.
Multiply N·m by 3/4 for a rough lbf·ft value: 100 N·m × 3/4 = 75, 1.7% above the exact 73.76.

- 1. Convert 1 N·m to the N·m base: 1 × 1 = 1 N·m.
- 2. Convert from N·m to lbf·ft: 1 ÷ 1.35581795 = 0.737562 lbf·ft.
- 3. Direct factor check: 1 × 0.73756215 = 0.737562 lbf·ft.
Torque and energy share the dimension N·m, but they are different physical quantities. Do not relabel torque as joules.

A quick note before you use the number
This converts units only; it does not prescribe a fastener tightening torque. Use the manufacturer or engineering specification for the required torque.
