Question

Define kilogram force

I am not understanding

Answer 1

The kilogram-force is a metric unit of force (kgf).

The kilogram-force is equal to a mass of one kilogram multiplied by the standard acceleration due to gravity on Earth, which is defined as exactly 9.80665 meter per second². Then one (1) kilogram-force is equal to 1 kg × 9.80665 meter per second² = 9.80665 kilogram × meter per second² = 9.80665 newton (1N)

a meter-kilogram-second unit of force, equal to the force that producesan acceleration equal to the acceleration of gravity, when acting on amass of one kilogram.
