To convert kilocalories per hour to milliwatts, multiply by 1162.222222.
The calculation uses 1 kcal/h = 1162.222222 mW. Results are displayed to at most 10 significant digits. Definitions can be exact while a displayed decimal is rounded. Match the displayed precision to your original measurement.
The formula
value in mW = value in kcal/h × 1162.222222
kcal/h- Input unit: kilocalories per hour
mW- Output unit: milliwatts
How to use this calculator
- Enter a value in kcal/h.
- Multiply by the stored conversion factor.
- Read the result in mW; divide by the same factor to convert back.
Worked examples
