Newton-meters to Foot-pounds Converter
Convert Newton-meters to foot-pounds instantly. Type an N·m value and get the exact ft·lb result. Formula: 1 N·m = 0.737562 ft·lb.
Newton-meters and foot-pounds are the two dominant torque units in the world, divided cleanly between metric and imperial engineering systems. One newton-meter equals exactly 0.7375621493 foot-pounds. In automotive engineering, engine torque is a critical performance specification. European car specs list torque in N·m; American specs use ft·lb. A high-performance sports car with 500 N·m of torque has 368.8 ft·lb — a figure American muscle car enthusiasts can contextualize. Iconic American V8 engines rated at 400 ft·lb produce 542.3 N·m. For fastener torque specifications (bolt tightening in engines, suspension components, and machinery), repair manuals published in different countries use different units. A cylinder head bolt torqued to 80 N·m per the European service manual should be compared to 59 ft·lb in an American translation. Getting this wrong — especially with aluminum components — can result in stripped threads or warped parts. Power tools like impact wrenches and torque wrenches have maximum torque ratings. A 100 ft·lb impact wrench delivers 135.6 N·m — important when matching tools to fastener requirements across metric and imperial hardware. In construction and structural engineering, connection bolt torques in metric drawings use N·m while US structural drawings use ft·lb or in·lb. A structural bolt torqued to 200 ft·lb is 271.2 N·m.

Frequently Asked Questions
How many foot-pounds is 1 Newton-meter?
1 N·m = 0.737562 ft·lb. Equivalently, 1 ft·lb = 1.35582 N·m. So multiply N·m by 0.7376 to get ft·lb.
What is 200 N·m in foot-pounds?
200 N·m = 147.51 ft·lb. This is a common engine torque output — a typical naturally aspirated 4-cylinder engine produces around 150–250 N·m (110–184 ft·lb).
Why do cars use both N·m and ft·lb for torque?
Different markets use different systems. European, Asian, and global car specifications use N·m (the SI unit). American spec sheets use ft·lb. Car manufacturers publish both for their international markets. The physical torque is identical — only the unit differs.
What is the difference between N·m and in·lb?
1 N·m = 8.8507 inch-pounds (in·lb). Inch-pounds are used for smaller fasteners and precision work (electronics, optical equipment). Foot-pounds and N·m are used for larger fasteners and engine components.
