Newton-meters to Foot-pounds Converter
Instantly convert torque values between N·m and ft·lb (also ft·lbf). Extra options for kN·m and in·lb for mechanics, automotive and construction use.
1 N·m = 0.737562149 ft·lb
Results
Foot-pound here means foot-pound force (lbf·ft).
Conversion formulas
ft·lb = N·m × 0.737562149
N·m = ft·lb × 1.355817948
in·lb = ft·lb × 12
kN·m = N·m ÷ 1000
These factors come from the definition: 1 ft = 0.3048 m and 1 lbf = 4.4482216152605 N, which gives the exact ft·lb ⇄ N·m relationship used in engineering references.

What is N·m?
The newton-meter (N·m) is the SI unit of torque (or moment). It’s the torque resulting from a 1 newton force applied at a perpendicular distance of 1 meter from the pivot.
What is ft·lb?
The foot-pound force (ft·lb or lbf·ft) is the imperial/US customary unit of torque. It’s the torque from 1 pound-force applied 1 foot away from the pivot.
Why convert between them?
Automotive service manuals, motorcycle torque specs and U.S. machinery often list ft·lb, whereas many torque wrenches or European/ISO documents list N·m. You need a precise converter to avoid under- or over-tightening bolts.
FAQ
1. Is ft·lb the same as lb·ft?
Practically yes — both refer to pound-force times distance. We use ft·lb here for clarity.
2. Are these exact values?
Yes, we use the exact physics-based conversion and only round for display. For critical engineering, keep extra decimals.
3. Can I enter inch-pounds directly?
Yes — pick “inch-pound (in·lb)” in the input, enter the value, and the tool will show N·m and ft·lb.
