• The joule is a standard SI unit for measuring work and energy which is also denoted as (J).
• It is equivalent to the work carried out by a one newton force moving through a metre.
• Joule was named in honour of the English physicist James Prescott Joule.
• 1 Joule= 1×10^7 erg in cgs unit.
• Joule is also the unit of heat.
• One joule is a very small unit of energy; it takes around 100,000 J to heat a cup of water from room temperature to boiling under normal circumstances.
• According to E=mc^2 with m = 1 kg and c = 299,792,458 m/s, one Kg of mass is equal to precisely 89,875,517,873,681,764 joules.

Therefore, Joule is unit used for work, energy and also heat.
