Formula: Kilogram-force Meter = Pound-force Foot × 0.1383
Multiply any Pound-force Foot value by 0.1383 to get Kilogram-force Meter.
Reverse: Pound-force Foot = Kilogram-force Meter × 7.233

1 lbf·ft = 0.1383 kgf·m.
Use N·m as the bridge: convert lbf·ft → N·m → kgf·m.
Multiply result by 7.233 to recover the original lbf·ft value.
Specifies engine torque output, drivetrain components, and wheel bolt torque in N·m and lbf·ft.
Designs fastener assemblies with torque specifications to achieve required bolt preload.
Selects motors and servos based on torque ratings in N·m or kgf·cm for joint actuation.
Calculates bending moments in beams and frames — moment = torque in structural analysis.
Follows torque charts in lbf·in and lbf·ft for airframe and engine fasteners per maintenance manuals.
Applies correct torque to flanges, pipe fittings, and coupling bolts using calibrated torque wrenches.
Pound-force foot (lbf·ft) is the standard Imperial torque unit in the United States, defined as the torque from a one pound-force applied one foot from the pivot. One lbf·ft = 1.35582 N·m.
lbf·ft dominates US automotive engineering: engine torque curves, wheel bolt torque specs, driveshaft specifications, and transmission ratings. A typical passenger car engine produces 150–300 lbf·ft; performance trucks can exceed 1,000 lbf·ft.
Interesting fact: The world's highest production-car torque record is held by the Dodge Ram TRX at 650 lbf·ft (881 N·m). Electric motors can deliver maximum torque instantly — Tesla Model S Plaid produces 1,020 lbf·ft (1,383 N·m).
Kilogram-force meter (kgf·m) is a traditional metric torque unit where the force is expressed as the weight of one kilogram under standard gravity. One kgf·m = 9.80665 N·m. It was widely used before SI standardization.
kgf·m remains in use in older machinery manuals, Japanese and Russian engineering documentation, and some legacy industrial specifications. A torque of 1 kgf·m equals the torque from 1 kg hanging 1 meter from a pivot.
Interesting fact: The kgf·m is sometimes loosely called 'meter-kilogram' or 'kilogram-meter' in older texts. The confusion between kgf (force) and kg (mass) is why SI replaced it with the newton-meter.
Converting Pound-force Foot to Kilogram-force Meter is common across automotive, mechanical, robotics, and structural engineering. Metric countries use N·m and kN·m; the US uses lbf·ft and lbf·in; robotics uses kgf·cm. Accurate conversion is essential when working with international workshop manuals, equipment specs, and torque wrenches.
Quick reference: 10 lbf·ft = 1.383 kgf·m. Reverse: 1 kgf·m = 7.233 lbf·ft. Exact factor: 1 lbf·ft = 0.1383 kgf·m.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
