Direct answer

1 cal = 4.184 J

J = cal × 4.184

Converter

Input

cal

Result

4.184J

J = cal × 4.184

cal = J × 0.239005736138

Example: 10 cal = 10 × 4.184 = 41.84 J.

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

1
Rewrite cal in the base unit
$1 cal = 4.184 J$
2
Rewrite J in the base unit
$1 J = 1 J$
3
Forward conversion
$1 cal = \frac{4.184 J}{1 J} \times 1 J = \frac{4.184}{1} J = 4.184 J$
4
Reverse conversion
$1 J = \frac{1 J}{4.184 J} \times 1 cal = \frac{1}{4.184} cal = 0.239005736138 cal$
