Short Answer

Expert verified
The unit for expressing mass is kilogram (kg) in SI units. The unit for expressing weight is Newton (N) in SI units.

Step by step solution

01

Identify Unit for Mass

Mass is a measure of the amount of matter in an object. In the International System of Units (SI), the base unit of mass is the kilogram (kg). Other units like gram (g), tonne (t), and milligram (mg) are also used in some contexts.
02

Weight is the force exerted by an object due to gravity. Unlike mass, it varies depending on the gravitational field. The SI unit of weight is the Newton (N). It can also be specified in pounds (lbs) in the imperial system.
