Reference

How force conversion works

Force equals mass times acceleration. Kilogram-force uses standard gravity and is not the same quantity as the kilogram mass unit.

Values are converted to newton first, then from that reference into the requested unit. Keeping a single documented reference reduces inconsistent pair-by-pair constants.

Accuracy note: Kilogram-force and pound-force use conventional standard gravity of exactly 9.80665 m/s².
