SI Unit of Weight
SI Unit of Weight is the Newton (N). The base unit is kgms-2 which is derived as follows:
- SI unit of Mass: kg
- SI unit of Acceleration: ms-2
As, Weight = Mass x Acceleration, we get,
SI unit of Weight = (SI unit of Mass) x (SI unit of Acceleration) = kgms-2
As per SI convention, the obtained unit i.e kgms-2 is unit of force which is named after the Scientist Sir Issac Newton as Newton. Thus, SI unit of weight is Newton (N).
Unit of Weight in Other Systems
The unit of weight in different systems is written as follows:
- MKS/SI System: kgms-2 or Newton (N)
- CGS System: dyne
- Other: Pound, Metric ton, Qunital, kilogram-force (kgf)
What is 1 Newton?
1 Newton is the force required to produce an acceleration of 1 ms-2 in a body of mass 1 kg.
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.
