Convert Pound-force feet to Newton metres
Convert Pound-force feet (lbf·ft) to Newton metres (N·m) instantly and accurately.
Conversion Formula
N·m = lbf·ft × 1.355817948
About Pound-force feet
The pound-force foot (lbf·ft) equals ≈ 1.35582 N·m, the dominant torque unit in North American automotive and mechanical engineering. SAE engine performance tests, US vehicle lug-nut torque specs (80-100 lbf·ft), and American industrial gearbox catalogs all use lbf·ft. V8 truck engines produce 400-600 lbf·ft; diesel pickups exceed 900 lbf·ft. 1 lbf·ft ≈ 1.35582 N·m = 12 lbf·in ≈ 192 ozf·in.
About Newton metres
The newton metre (N·m) is the SI coherent derived unit of torque and bending moment. Car engine torque is commonly quoted in N·m - a family hatchback delivers 150-250 N·m; a performance saloon 400-600 N·m. Fastener pre-load torques, EV traction-motor ratings, and structural connection bolt specifications are all given in N·m. 1 N·m = 100 N·cm = 1000 N·mm ≈ 0.7376 lbf·ft ≈ 8.851 lbf·in.
