What is kilogram-force (kgf)?

Kilogram-force is a gravitational unit of force representing the weight of one kilogram under standard gravity and equals 9.80665 newtons.

Why use ton-force (long) for force measurements?

Ton-force (long) reflects the force of one long ton under standard gravity and is used in historical British engineering and naval force specifications.

Can the converter handle scientific force units like newtons?

This converter specifically converts between kilogram-force and ton-force (long) and does not directly convert scientific SI units like newtons.
