Turn the megajoules to joules. The prefix "Mega" means six, therefore, to count the number of megajoules to joules, you have the original number times 10 to the sixth power, that is, 1 000 000. For example, switch 9

**MJ**to**Kcal**. 9 MJ is 9*1 000 000 = 9 000 000 joules. Next, you need to know what calories you need to translate joules, as is the concept of "calorie international" and the concept of "thermochemical calorie". One Joule corresponds to 0,238846 calories or 0,239006 international calorie thermochemical.2

Translate joules into calories international of using known coefficient of translation: 1 j ≈ 0,238846 calories. In this example, multiply 9 000 000 joules at 0, 238 846, get 2 149 614 cal. Put the resulting number of calories in kilocalories by dividing it by 1 000, get 2 149,6 kilocalories (Kcal). Thus, 9 megajoules fits 2149, 6 calories international. Quickly convert MJ to Kcal is to multiply the original number of MJ by a factor of 238,846 (0,238846*1 000). In this case: 9 MJ*238,846 = 2149,6 Kcal.

Translate joules to thermochemical calories using the conversion factor: 1 j ≈ 0,239006 calories. In this example, multiply 9 000 000 joules on 0,239006, get 2 151 054 2 151,1 cal or Kcal. Thus, 9 megajoules corresponds to 2151,1 calories thermochemical.

To translate joules into calories, you need to know that 1 calorie corresponds to 4,1868 joules, 1 calorie - 4,1840 joules. Translate calories into joules by multiplying them by the coefficients. For example, calories 500 international matches (500 * 4,1868) 2 093,4 Joule, and 500 thermochemical calories (500 * 4,1840) 2 092 Joule.
