  2. Multiply by 737.561 to perform the conversion.
  3. The result is your value expressed in Foot-pounds-force (ft·lbf).

Conversion Factor

1 kN·m = 737.561 ft·lbf

Reverse Factor

1 ft·lbf = 0.00135582 kN·m

Worked Example

Convert 25 Kilonewton-meters to Foot-pounds-force: 25 kN·m = 18439 ft·lbf

About Kilonewton-meter (kN·m)

A metric unit of torque equal to 1,000 newton-meters. Kilonewton-meters are used for large-scale engineering: industrial turbines, large diesel engines (ship propulsion, locomotives), wind-turbine main shaft torque (a modern 5 MW wind turbine produces ~3,800 kN·m), structural moments on reinforced concrete beams, and crankshaft loads in heavy equipment. Structural design codes (Eurocode, ASCE) use kN·m for bending moments.

About Foot-pound-force (ft·lbf)

An imperial unit of torque equal to one pound-force applied at a one-foot lever arm (about 1.356 N·m). Foot-pounds are the dominant US torque unit — automotive service manuals, wheel-lug torque specs, US-made torque wrenches, and firearms barrel-threading all list ft·lbf. A typical car's lug nut spec is 80–100 ft·lbf. Careful: ft·lbf as torque should not be confused with ft·lb as energy (same name, different dimension).

Understanding Kilonewton-meters

The Kilonewton-meter (symbol: kN·m) is a unit of torque. A metric unit of torque equal to 1,000 newton-meters. Kilonewton-meters are used for large-scale engineering: industrial turbines, large diesel engines (ship propulsion, locomotives), wind-turbine main shaft torque (a modern 5 MW wind turbine produces ~3,800 kN·m), structural moments on reinforced concrete beams, and crankshaft loads in heavy equipment. Structural design codes (Eurocode, ASCE) use kN·m for bending moments.

It belongs to the metric measurement system.

Kilonewton-meters are commonly used in automotive maintenance, structural engineering, and manufacturing.

Understanding Foot-pounds-force

The Foot-pound-force (symbol: ft·lbf) is a unit of torque. An imperial unit of torque equal to one pound-force applied at a one-foot lever arm (about 1.356 N·m). Foot-pounds are the dominant US torque unit — automotive service manuals, wheel-lug torque specs, US-made torque wrenches, and firearms barrel-threading all list ft·lbf. A typical car's lug nut spec is 80–100 ft·lbf. Careful: ft·lbf as torque should not be confused with ft·lb as energy (same name, different dimension).

It belongs to the imperial measurement system.
