Here's why:
* Kilogram-weight (kgwt) is a unit of force that represents the force of gravity acting on a 1 kilogram mass.
* Newton (N) is the standard unit of force in the International System of Units (SI).
* Acceleration due to gravity (g) on Earth is approximately 9.81 m/s².
Therefore, 1 kgwt is equivalent to the force of gravity acting on a 1 kg mass, which is:
* Force = mass x acceleration
* Force = 1 kg x 9.81 m/s² = 9.81 N
