Formula: Kilogram-force Centimeter = Pound-force Inch × 1.152
Multiply any Pound-force Inch value by 1.152 to get Kilogram-force Centimeter.
Reverse: Pound-force Inch = Kilogram-force Centimeter × 0.868

Use N·m as the bridge: convert lbf·in → N·m → kgf·cm.
Multiply result by 0.868 to recover the original lbf·in 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 inch (lbf·in) equals 1/12 of lbf·ft (0.112985 N·m) and is used for small fasteners, electronics, precision instruments, and applications where lbf·ft would be impractically small.
lbf·in is standard for small fasteners in electronics manufacturing, firearms assembly, and precision instruments. Torque screwdrivers for electronics typically range from 0.5–20 lbf·in. Aircraft fastener specifications often use in·lbf.
Interesting fact: Overtorquing small electronics screws (which often need only 1–3 lbf·in) is a leading cause of cracked PCBs and stripped threads in consumer electronics assembly.
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 Inch 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·in = 11.52 kgf·cm. Reverse: 1 kgf·cm = 0.868 lbf·in. Exact factor: 1 lbf·in = 1.152 kgf·cm.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
