Other than the generalized definition of energy, the ability of a system to perform work, there are various definitions of energy, based on different disciplines, like the thermal energy, electromagnetic, nuclear, radiant energy.
If you observe closely, you will know, the generalized definition is quite baffling, as energy not all the time is necessarily available to do work. That is why different fields have their own definitions that are convenient.
According to the International System of Units, also known as SI units, joules is the unit of energy, that is, energy is measured by this unit.

The SI defines Joules in mechanical terms. It says one joule is the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton. However, Joules is not the only unit, there are many such as, gigajoule, megaelectron-volt, erg, horsepower, calories, including others.

These variations have made energy unit conversions indispensable. At our, all common or uncommon units are given in the table to convert energy units, just enter the value and have a corresponding value in your desired unit. It is simple as that. 
All this can be done easily with the help of this online conversions tool.
