0.000239005736kcal

kcal = J × 0.000239005736

J = kcal × 4,184

Example: 10 J = 10 × 0.000239005736 = 0.002390057361 kcal.

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

1
Rewrite J in the base unit
$1 J = 1 J$
2
Rewrite kcal in the base unit
$1 kcal = 4, 184 J$
3
Forward conversion
$1 J = \frac{1 J}{4 , 184 J} \times 1 kcal = \frac{1}{4 , 184} kcal = 0.000239005736 kcal$
4
Reverse conversion
$1 kcal = \frac{4 , 184 J}{1 J} \times 1 J = \frac{4 , 184}{1} J = 4, 184 J$
