Weight vs Mass
While we call this a weight converter, it actually converts between mass units. In everyday language, the terms 'weight' and 'mass' are often used interchangeably, although they have different scientific meanings.
MassMass is the amount of matter in an object, measured in units like kilograms. It remains constant regardless of location.
WeightWeight is the force exerted on an object due to gravity, measured in newtons. It varies depending on gravitational forces.
