Convert Pound-feet to Kilogram-force Centimeters

Formula

kgf·cm = lbf·ft × 13.8254954376

Derivation from SI units:

• 1 lbf·ft = 4.4482216152605 N × 0.3048 m = 1.3558179483314 N·m
• 1 kgf·cm = 9.80665 N × 0.01 m = 0.0980665 N·m (exact)
• 1 lbf·ft = 1.355817948331 N·m ÷ 0.0980665 N·m per kgf·cm = 13.8254954376 kgf·cm

Both units are defined exactly, so the factor is exact. Pound-foot definition: pound-foot; Kilogram-force Centimeter definition: kilogram-force centimeter.

Worked examples

1. A reading of 30 lbf·ft converts to 414.7648631 kgf·cm.
   30 lbf·ft × 13.82549544 = 414.7648631 kgf·cm
2. A value of 200 lbf·ft is 2765.099088 kgf·cm.
   200 lbf·ft × 13.82549544 = 2765.099088 kgf·cm

Where it's used

Pound-feet are used for US car wheel-lug and bolt torques, while kilogram-force centimeters appear in RC servo torque ratings (e.g. 13 kg·cm). Both measure torque (moment of force), so the conversion is a fixed factor.
