The units of mass and of force are different, so the quantities cannot be equated.
Work Step by Step
A mass of 1 kg feels a downward force of 2.2 lb when it is near the Earth’s surface. However, in different places, a 1-kg mass would have different weights.
Equating the two would be akin to saying that a car equals 10 m/s just because it sometimes moves at that velocity.
