What is Unit of Weight?
Unit of Weight is the measurement of magnitude of weight according to defined standards or convention. As mentioned above, the formula for weight is mass multiplied by acceleration due to gravity. Thus, it gives the base unit of weight as kgms-2 as unit of mass is kg and that of acceleration is ms-2.
Also, we know that weight is a type of force which implies that SI unit of weight is Newton, i.e. N. Some other commonly used units of weight are kilogram-force (kgf) and dyne.
Dimensional Formula of Weight
The dimensional formula for weight is [M1 L1 T-2]. It can be derived using the formula of weight as follows.
Weight = (Mass) × (Acceleration due to Gravity)
Substituting the dimensional formula of mass and acceleration we get,
Dimension of Weight = [M1 L0 T0] x [M0 L1 T-2]
Dimension of Weight = [M1 L1 T-2]
Unit of Weight
Unit of Weight is Newton represented as N, which is also known as the force of gravity on a mass. Weight of the body is the gravitational force by which the earth or any other planet attracts the body. Other weight units are pound-force, metric ton, slug, quintal, kilogram-force (kgf) and dyne.
In this article, we will discuss the definition of weight, unit of weight, conversion between the unit of weight in various systems, and some sample problems related to the unit of weight.
