How to Convert Megawatt to Kilocalorie per Hour
- 1 MW = 859845.2279 kcal/h
- 1 kcal/h = 0.000001163 MW
- Example: convert 15 MW to kcal/h: 15 MW = 15 × 859845.2279 kcal/h = 12897678.42 kcal/h
Reference conditions. kcal/h: Uses the International Table kilocalorie (4186.8 J), the convention in heating and HVAC: 1 kcal/h = 1.163 W.
Formula
kcal/h = MW × 859845.227859
Derivation from SI units:
- 1 MW = 10⁶ W
- 1 kcal_IT/h = 4186.8 J ÷ 3600 s = 1.163 W (exact)
- 1 MW = 1000000 W ÷ 1.163 W per kcal/h = 859845.227859 kcal/h
Both units are defined exactly, so the factor is exact. Megawatt definition: megawatt; Kilocalorie per Hour definition: kilocalorie per hour.
Worked examples
- A reading of 3 MW converts to 2579535.684 kcal/h.
3 MW × 859845.2279 = 2579535.684 kcal/h - A value of 50 MW is 42992261.39 kcal/h.
50 MW × 859845.2279 = 42992261.39 kcal/h

Frequently asked questions
How many kilocalories per hour are in 1 megawatt?
1 MW = 859845.2279 kcal/h.
How do I convert megawatts to kilocalories per hour?
Multiply the value in MW by 859845.2279. For example, 15 MW × 859845.2279 = 12897678.42 kcal/h.
Is the MW to kcal/h conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
