Before understanding the unit of mass it is very crucial for students to know what is mass. In simple terms, mass is the quantity of matter in an object. More significantly, it can be both a property of a physical body and a measure of its resistance to acceleration when some amount of force is applied. However, one important point students should remember here is that mass is different from weight even though the terms are sometimes used interchangeably. Also, they have different units. Let’s look at them below.
What Is Mass?
Mass is defined as the matter that is present in the given object. Following are the most commonly used units for the measurement of mass:
SI Unit of Mass
The standard SI unit of mass is as:
Other Units of Mass
Other units that are accepted for use in SI are gram (g) and its multiples and submultiples, a tonne (t) (or “metric ton”), electronvolt (eV), the atomic mass unit (u) which is most convenient for expressing the masses of atoms and molecules.
