1. The distinction between kgf and kg lies in their representation of different physical quantities. kgf stands for kilogram-force, a unit of force, whereas kg represents mass.
2. In engineering and physics, kgf is commonly used as a unit of force. It signifies the force experienced by an object due to gravity on Earth's surface.
3. Despite their numerical equivalence for a 1kg object, which experiences a force of 1kgf, kgf and kg have distinct physical meanings and should not be interchanged.
4. In terms of force conversion, 1 newton equals 0.102 kilogram-force, while 1 kilogram-force is equivalent to 9.8 newtons. This conversion is crucial in engineering calculations.
5. Other units of force, such as pound-force, dyne, and so on, have their specific applications, just like newtons and kilogram-force. The newton is the legal unit of force within the International System of Units (SI).
6. Historically, China used kilogram-force as one of the units of force, but with the widespread adoption of the International System of Units, the newton has become the preferred standard unit of force.
