How to convert newton metres to pound-feet
One newton metre equals 0.737562 pound-feet, so multiply the number of newton metres by 0.737562:
lb·ft = N·m × 0.737562
N·m = lb·ft ÷ 0.737562 (1 lb·ft = 1.3558 N·m)
Example: 25 N·m → 25 × 0.737562 = 18.4391 lb·ft.
Going the other way, divide by 0.737562, or multiply by 1.3558; the pound-feet to newton metres converter does it for you.
Everyday values
| Newton metres | Pound-feet | For example |
|---|---|---|
| 25 N·m | 18.4391 lb·ft | a spark plug, roughly (check the manual) |
| 110 N·m | 81.1318 lb·ft | a typical car wheel nut, roughly |
| 150 N·m | 110.634 lb·ft | a small car engine |
| 300 N·m | 221.269 lb·ft | a turbo or diesel car engine |
| 600 N·m | 442.537 lb·ft | a large diesel pickup |
When you need this conversion
Torque wrenches, engine specifications and bolt-tightening charts use both units. Always use the exact value from the service manual for your vehicle; the "roughly" values in the table are only typical examples. For engine power, see the horsepower and torque calculator.

About the units
- Newton metre (N·m): the torque of 1 newton acting 1 metre from the axis.
- Pound-foot (lb·ft): 1 pound-force acting 1 foot from the axis, about 1.3558 N·m.
Both are units of torque. The conversion factor comes from the exact definitions above, so the calculator is exact; results are only rounded for display (up to six significant digits).
