12 kcal of energy is released when one gram of charcoal is burned. 1 kcal is equal to 1000 cal. This gives the number of calories of energy released when 1 g of charcoal is burned as 12000 cal.

For a kilogram or 1000 g of charcoal the energy released is equal to 12000*1000 = 12*10^6 calories.

12*10^6 or 12 million calories or energy are released when 1 kg of charcoal is burned.
