Formula: Kilogram-force Centimeter = Pound-force Foot × 13.83
Multiply any Pound-force Foot value by 13.83 to get Kilogram-force Centimeter.
Reverse: Pound-force Foot = Kilogram-force Centimeter × 0.07233

1 lbf·ft = 13.83 kgf·cm.
Use N·m as the bridge: convert lbf·ft → N·m → kgf·cm.
Multiply result by 0.07233 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 centimeter (kgf·cm) equals 0.01 kgf·m = 0.0980665 N·m. It is used for small motors, servos, and precision mechanical components, particularly in Japanese and Asian engineering datasheets.
RC servo motors, stepper motors, and small gear motors are commonly rated in kgf·cm. A typical hobby servo produces 3–10 kgf·cm; industrial servos range from 100 to 10,000 kgf·cm.
Interesting fact: A servo motor rated at 10 kgf·cm can hold a 10 kg weight at the end of a 1 cm arm — or equivalently, 1 kg at the end of a 10 cm arm. This intuitive interpretation is why kgf·cm persists in robotics and hobby electronics.
Converting Pound-force Foot to Kilogram-force Centimeter 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 = 138.3 kgf·cm. Reverse: 1 kgf·cm = 0.07233 lbf·ft. Exact factor: 1 lbf·ft = 13.83 kgf·cm.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
