✳Joule, unit of work or energy(heat) in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 10^7 ergs, which means cgs unit of work.

✳We know, Work= Force× distance

Then, 1 Joule= 1 N× 1 m

=>1 J= 1Nm

✴One joule can also be defined as the following:

✏The work required to move an electric charge of one coulomb through an electrical potential difference of one volt, or one coulomb-volt (C⋅V). This relationship can be used to define the volt.

✏The work required to produce one watt of power for one second, or one watt-second (W⋅s) (compare kilowatt-hour – 3.6 megajoules). This relationship can be used to define the watt.
