The Newton-Meters to Foot-Pounds Converter converts torque values from newton-meters (N·m) to foot-pounds (ft·lb) using the conversion factor 1 N·m = 0.737562 ft·lb. This is the most frequently needed torque conversion for engineers, mechanics, and technicians working between metric and imperial torque specifications.
Newton-meters are the SI standard for torque, used in international automotive specifications (ISO/DIN standards), European engineering, and scientific research. Foot-pounds are the American standard, used extensively in US automotive repair manuals, aerospace specifications, SAE standards, and construction bolt specifications. Nearly every torque wrench sold in North America displays both N·m and ft·lb scales.
This conversion is critically important in automotive maintenance. Modern vehicles often have components designed to metric specifications (engine, transmission) alongside imperial specifications (some body and chassis hardware). A mechanic must accurately convert between N·m and ft·lb to apply correct torque, preventing both under-tightening (which risks loosening and failure) and over-tightening (which risks stripping, cracking, or fatigue).
Our converter also provides results in inch-pounds (in·lb), which are used for smaller fasteners where foot-pounds would give inconveniently small numbers. The relationship is exact: 1 ft·lb = 12 in·lb.
The formula is: ft·lb = N·m × 0.737562 (or equivalently, N·m ÷ 1.35582). For inch-pounds: in·lb = N·m × 0.737562 × 12 = N·m × 8.85075. A useful approximation: multiply N·m by 0.74 or divide by 1.36 for a quick mental estimate within 1% accuracy.
Common automotive torque values: wheel lug nuts 100-140 N·m (74-103 ft·lb), spark plugs 15-30 N·m (11-22 ft·lb), cylinder head bolts 60-100 N·m (44-74 ft·lb), oil drain plug 30-50 N·m (22-37 ft·lb). Engine output: typical car 200-400 N·m (148-295 ft·lb), sports car 500-800 N·m (369-590 ft·lb).

1 N·m = 0.737562 ft·lb. Conversely, 1 ft·lb = 1.35582 N·m.
Multiply by 0.74 (or divide by 1.36) for a quick estimate within 1% accuracy. For example, 100 N·m ≈ 74 ft·lb (exact: 73.76).
Typically 80-140 N·m (59-103 ft·lb) depending on the vehicle. Always check your owner's manual for the exact specification.
Because both units are widely used. Metric vehicles (most modern cars) specify N·m, while many US-market vehicles and older manuals use ft·lb. Dual-scale wrenches work for either.
Dimensionally they are equivalent (both are kg·m²/s²), but they represent different physical concepts. Torque is a rotational force vector; energy is a scalar. The units are kept separate to avoid confusion.
50 N·m = 36.878 ft·lb. This is a common torque for medium-sized bolts.
Set the desired value, then turn the bolt until the wrench clicks, flexes, or indicates the target is reached. Digital wrenches display the current torque in real time.
Typically 15-30 N·m (11-22 ft·lb) for most passenger vehicles. Aluminum cylinder heads usually require lower torque than cast iron.
Yes. Over-tightening can stretch bolts past their yield point, strip threads, crack castings, or cause bolt fatigue failure. Always use a torque wrench for critical fasteners.
200 N·m = 147.512 ft·lb. This is in the range of many engine component specifications.
