Frequently Asked Questions

About Kilogram-force Meter and Kilonewton-meter

Kilogram-force Meter (kgf·m)

Kilogram-force meter (kgf·m) is a traditional metric torque unit where the force is expressed as the weight of one kilogram under standard gravity. One kgf·m = 9.80665 N·m. It was widely used before SI standardization.

kgf·m remains in use in older machinery manuals, Japanese and Russian engineering documentation, and some legacy industrial specifications. A torque of 1 kgf·m equals the torque from 1 kg hanging 1 meter from a pivot.

Interesting fact: The kgf·m is sometimes loosely called 'meter-kilogram' or 'kilogram-meter' in older texts. The confusion between kgf (force) and kg (mass) is why SI replaced it with the newton-meter.

Kilonewton-meter (kN·m)

The kilonewton-meter (kN·m) equals 1,000 N·m and is used for large-scale torque in structural engineering, heavy machinery, and civil infrastructure. Bridge bolts, crane slewing rings, and wind turbine gearboxes operate in the kN·m range.

Structural engineering uses kN·m for bending moments in beams, columns, and foundations. A typical car wheel bolt is torqued to about 0.1 kN·m; a large wind turbine main shaft may experience torques of 1,000–10,000 kN·m.

Interesting fact: The torque needed to loosen a rusted M24 bolt in civil construction can exceed 1 kN·m. The main rotor shaft of a 5 MW offshore wind turbine transmits over 4,000 kN·m of torque in high winds.

About Kilogram-force Meter to Kilonewton-meter Conversion

Converting Kilogram-force Meter to Kilonewton-meter 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 kgf·m = 0.09807 kN·m. Reverse: 1 kN·m = 102 kgf·m. Exact factor: 1 kgf·m = 0.009807 kN·m.

All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
