About these units
Short background on the units used in this conversion.
Kilogram-Force (kgf)
The kilogram-force (kgf) is the gravitational force on one kilogram of mass at standard gravity — exactly 9.80665 newtons.
Kilograms-force appear on old spring scales and some Asian industrial specs; do not confuse with kilograms of mass.
