How much is weight is 144 KG?

Weight is a measure of the force of gravity acting on an object's mass. In this case, 144 kilograms (kg) is a measure of mass, not weight. Weight is calculated by multiplying mass by the acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth. Therefore, the weight of a 144 kg object on Earth would be approximately 144 kg * 9.81 m/s^2 = 1412.64 Newtons.
