Convert Kilogram-force Meters to Kilonewton-meters

Formula

kN·m = kgf·m × 0.00980665

or kN·m = kgf·m ÷ 101.9716212978

Derivation from SI units:

• 1 kgf·m = 9.80665 N × 1 m = 9.80665 N·m (exact)
• 1 kN·m = 10³ N·m
• 1 kgf·m = 9.80665 N·m ÷ 1000 N·m per kN·m = 0.00980665 kN·m

Both units are defined exactly, so the factor is exact. Kilogram-force Meter definition: kilogram-force meter; Kilonewton-meter definition: kilonewton-meter.

Worked examples

1. A reading of 10 kgf·m converts to 0.0980665 kN·m.
   10 kgf·m × 0.00980665 = 0.0980665 kN·m
2. A value of 30 kgf·m is 0.2941995 kN·m.
   30 kgf·m × 0.00980665 = 0.2941995 kN·m

Where it's used

Kilogram-force Meters are used for older Japanese and European engine torque specs, while kilonewton-meters appear in structural bending moments. Both measure torque (moment of force), so the conversion is a fixed factor.
