In simple words, energy can be described as the ability to perform work. It can take many different forms, including kinetic, potential, electrical, chemical, radioactive, thermal, and others. There are two types of energy: renewable and non-renewable. We'll also go through the different types of energy units in this article.
The table of SI units is as follows:
SI Unit = Joules
Surprisingly, the name of this worldwide unit is preserved in commemoration of James Prescott Joule, a British physicist whose contributions to the development of the energy idea were important. When we look at the unit in its simplest form, 1-N.m equals 1 Joule, and in SI base units, it may be written as:
The unit table of the CGS system is as follows:
CGS Unit = erg
The erg is a unit of energy equal to 10⁻⁷ J. An erg is the amount of work performed by a single dyne over a one-centimeter distance.

The unit table of the MKS system is as follows:
MKS unit = Joule
Energy units can be preceded by a variety of elements, and different units are typically used to measure energy. The following are some examples of common units:
The following is a table with a list of energy conversions:
Unit | Joule | Calorie | BTU | Kilowatt-hour |
Joule | 00 | 0.2390 | 0.000948 | 2.77778E-07 |
Calorie | 4.187 | 00 | 0.00397 | 1.16279E-06 |
BTU | 1055 | 252 | 00 | 0.000293 |
Kilowatt-hour | 3.6E6 | 8.6E5 | 3412 | 00 |
The commercial unit of energy is the kilowatt-hour.
The SI unit of energy becomes little when huge amounts of energy need to be expressed. As a result, the commercial unit is employed.
When the units of force and length are doubled, the unit of unit energy grows fourfold.
The following is the relationship between energy, force, and distance:
The commercial unit of energy is the kilowatt-hour (kWh). The quantity of energy utilised by a device in one working hour at a constant rate of one kilowatt is defined as one kilowatt-hour.
The Joule is the SI unit of energy.
As a result, the following is the relationship between the commercial and SI units of energy:
1 kWh = 1kW x 1h = 1000W x 1h = 1000(J/s) x 3600 s = 3.6 x106 J
3.6 106 Joules equals one unit of electrical energy.
When a spring is either drawn out or squeezed, it will have the most energy.
One joule equals 10⁻⁷ ergs.
Potential energy is exemplified by the following examples:
The different types of kinetic energy are as follows:
