UnitSnapNewton Meters to Pound-Force Feet
1 N·m = 0.7375621 lbf·ft
Service manuals from European and Asian manufacturers, and most engine spec sheets worldwide, list torque in newton meters. Many torque wrenches sold in the United States are scaled in foot-pounds, so converting N·m to lbf·ft lets mechanics tighten fasteners to specification.
When you need to convert newton meters to pound-force feet
- Setting a foot-pound torque wrench to a metric service manual spec
- Comparing engine torque figures from European and US reviews
- Tightening bicycle components specified in N·m with a US wrench
- Translating electric motor torque ratings for US customers
How to convert newton meters to pound-force feet
lbf·ft = N·m × 0.7375621
Example: 5 N·m = 3.687811 lbf·ft
Common torque specs in N·m
| Newton Meters (N·m) | Pound-Force Feet (lbf·ft) |
|---|---|
| 5 N·m | 3.687811 lbf·ft |
| 10 N·m | 7.375621 lbf·ft |
| 25 N·m | 18.43905 lbf·ft |
| 50 N·m | 36.87811 lbf·ft |
| 100 N·m | 73.75621 lbf·ft |
| 120 N·m | 88.50746 lbf·ft |
| 150 N·m | 110.6343 lbf·ft |
| 200 N·m | 147.5124 lbf·ft |
| 400 N·m | 295.0249 lbf·ft |
Tips for converting newton meters to pound-force feet
- Multiply N·m by about 0.74 to get lbf·ft. Taking three quarters is a quick estimate within 2%.
- Small bicycle and electronics specs in N·m often convert better to inch-pounds; 1 lbf·ft equals exactly 12 lbf·in.
- Engine torque and fastener torque use the same unit, but an incorrect fastener setting can strip threads, so round conservatively.
