Calories to Megawatt-hours Converter

Convert calories (thermochemical) (cal) to megawatt-hours (MWh), with the formula, a conversion table and exact factors.

Change the values and press Calculate to work out your own figures.

Enter an amount of energy, choose its unit and the unit you want. The answer is exact until it is shown, and the same value appears in every other unit.

A number, fraction (3/8), mixed number (1 1/2), scientific notation (2.5e6) or a simple sum such as 2*3.
The unit you want the answer in. Swap exchanges the two units.

1 cal = 1.16222222222 × 10⁻⁹ MWh

Show the working
  1. 1 cal = 1.16222222222e-9 MWh
  2. 1 × 1.16222222222e-9 = 1.16222222222e-9 MWh

How to convert calories to megawatt-hours

1 cal = 1.16222222222 × 10⁻⁹ MWh, so multiply by 1.16222222222 to go from calories (thermochemical) to megawatt-hours. Going the other way, 1 MWh = 860,420,650.096 cal.

MWh = cal × 1.16222222222
cal = MWh × 860,420,650.096

Worked example:

1 cal = 1.16222222222e-9 MWh
5 × 1.16222222222e-9 = 5.81111111111e-9 MWh

About the units

Calories (cal)
Calories (thermochemical), a specialised unit. The thermochemical calorie, 4.184 J, used on US food labels as 1 Calorie = 1 kilocalorie. Definition: NIST SP 811 Appendix B.8, factors for units listed alphabetically.
Megawatt-hours (MWh)
Megawatt-hours, a metric unit. Definition: BIPM SI Brochure, 9th edition (SI units, prefixes and units accepted for use with the SI).
