1 MJ = 0.239005736138 Mcal

Show the working
  1. 1 MJ = 0.239005736138 Mcal
  2. 1 × 0.239005736138 = 0.239005736138 Mcal

How to convert megajoules to megacalories

1 MJ = 0.239005736138 Mcal, so multiply by 0.239005736138 to go from megajoules to megacalories. Going the other way, 1 Mcal = 4.184 MJ.

Mcal = MJ × 0.239005736138
MJ = Mcal × 4.184

Worked example:

1 MJ = 0.239005736138 Mcal
5 × 0.239005736138 = 1.19502868069 Mcal
