Result

0.239005736138kcal

kcal = kJ × 0.239005736138

kJ = kcal × 4.184

Example: 10 kJ = 10 × 0.239005736138 = 2.39005736138 kcal.

Express both kJ and kcal in the same base unit J (joule), then cancel the shared base unit.

1
Rewrite kJ in the base unit
$1 kJ = 1, 000 J$
2
Rewrite kcal in the base unit
$1 kcal = 4, 184 J$
3
Forward conversion
$1 kJ = \frac{1 , 000 J}{4 , 184 J} \times 1 kcal = \frac{1 , 000}{4 , 184} kcal = 0.239005736138 kcal$
4
Reverse conversion
$1 kcal = \frac{4 , 184 J}{1 , 000 J} \times 1 kJ = \frac{4 , 184}{1 , 000} kJ = 4.184 kJ$
