How to convert kilocalories to kilowatt-hours
Formula: kWh = kcal × 0.00116222
Worked example: 500 kcal → 500 × 0.00116222 = 0.581111 kWh
One kWh is about 860 kcal. A 75 kg person cycling at moderate effort burns roughly 500 kcal an hour, or only about 0.58 kWh, which shows how much energy electricity delivers for a few cents.
