SI Unit of Energy
In the International System of Units (SI), joule is the universal unit of energy. It is versatile and applies to various energy forms.
The joule is integral to scientific, engineering, and practical applications because it provides a standard measure for energy transactions in physical processes.
Whether it is the energy consumed by electrical appliances, the calories burned during exercise, or the heat required to raise the temperature of a substance, the joule serves as a common denominator for quantifying energy.
What is 1 Joule?
One joule is defined as the amount of energy transferred when a force of one newton moves an object one meter in the direction of the force.
Unit of Energy in CGS System
The unit of energy in the CGS system is the erg (erg). In the SI system, the standard unit of energy is the Joule (J). The conversion factor between these units is 1 Joule = 10⁷ ergs.
Dimensional Formula of Energy
The dimensional formula of energy is [M¹L²T⁻²]
where:
- M represents mass
- L represents length
- T represents time
Unit of Energy
Unit of energy is a standard quantity used to measure the work done by a force or the amount of heat transferred. The SI unit of energy is the joule (J). Other Units of energy are electronvolt (eV), calorie, BTU, etc
In this article, we will define energy, discuss possible units to measure it, SI unit of energy, Conversion of energy unit, and some solved examples based on it.
