Convert Kilogram-force Centimeters to Newton-centimeters

Formula

N·cm = kgf·cm × 9.80665

Derivation from SI units:

• 1 kgf·cm = 9.80665 N × 0.01 m = 0.0980665 N·m (exact)
• 1 N·cm = 0.01 N·m
• 1 kgf·cm = 0.0980665 N·m ÷ 0.01 N·m per N·cm = 9.80665 N·cm

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

Worked examples

1. A reading of 10 kgf·cm converts to 98.0665 N·cm.
   10 kgf·cm × 9.80665 = 98.0665 N·cm
2. A value of 25 kgf·cm is 245.16625 N·cm.
   25 kgf·cm × 9.80665 = 245.16625 N·cm

Where it's used

Kilogram-force Centimeters are used for RC servo torque ratings (e.g. 13 kg·cm), while newton-centimeters appear in dental and medical implant torque (e.g. 35 N·cm). Both measure torque (moment of force), so the conversion is a fixed factor.
