1gm fat = 9.3kcal,
1 kcal = 4.2joules,
9.3kcal = 9.3*4.2 = 39.06kJ.
1 kcal = 4.2joules,
9.3kcal = 9.3*4.2 = 39.06kJ.

@All.
1 calorie = 4.2 joule is correct.
1-kilo calorie = 4.2 joule is wrong.
That's why 1 gram releases 9.3 kilocalorie of energy.
= 9.3 *kilo* 4.2 joule.
= 39.06 kilo joule.
=39.06 kJ.
1 calorie = 4.2 joule is correct.
1-kilo calorie = 4.2 joule is wrong.
That's why 1 gram releases 9.3 kilocalorie of energy.
= 9.3 *kilo* 4.2 joule.
= 39.06 kilo joule.
=39.06 kJ.

1 gm fat releases 9.3 kcal.
So energy produced by 1 gm fat is 9.3x4.2 = 39.06. As 1 kcal = 4.2 kj.
So energy produced by 1 gm fat is 9.3x4.2 = 39.06. As 1 kcal = 4.2 kj.

0.004184 kilojoules 1 calorie = 0.004184*1000 = 4.184~4.2
