239,005.736138cal

cal = MJ × 239,005.736138

MJ = cal × 0.000004184

Example: 10 MJ = 10 × 239,005.736138 = 2,390,057.36138 cal.

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

1
Rewrite MJ in the base unit
$1 MJ = 1, 000, 000 J$
2
Rewrite cal in the base unit
$1 cal = 4.184 J$
3
Forward conversion
$1 MJ = \frac{1 , 000 , 000 J}{4.184 J} \times 1 cal = \frac{1 , 000 , 000}{4.184} cal = 239, 005.736138 cal$
4
Reverse conversion
$1 cal = \frac{4.184 J}{1 , 000 , 000 J} \times 1 MJ = \frac{4.184}{1 , 000 , 000} MJ = 0.000004184 MJ$
