Complete combustion of 2.0 metric tons of coal to gaseous carbon dioxide releases 6.6X10¹⁰ J of heat. Convert this energy to
Taya2010 [7]

First of all we should know that, 1 Joule = 0.000239 kilocalories.

So, 6.6×10^{10} J = 6.6×10^{10} × 0.000239 kilocalories

      6.6×10^{10} J = 15774000 kilocalories

                       = 1.58 × 10^{7} kilocalories

One joule is described as the quantity of electricity exerted when a pressure of 1 newton is implemented over a displacement of 1 meter. Within the SI machine, the unit of labor or electricity is the Joule.
