- 1 cal = 1e-6 Mcal
- 1 × 1e-6 = 1e-6 Mcal
How to convert calories to megacalories
1 cal = 1 × 10⁻⁶ Mcal, so multiply by 1 to go from calories (thermochemical) to megacalories. Going the other way, 1 Mcal = 1,000,000 cal.
Mcal = cal × 1 cal = Mcal × 1,000,000
Worked example:
1 cal = 1e-6 Mcal 5 × 1e-6 = 5e-6 Mcal
