Kilowatt-hour to Gram calorie Formula & Unit Definitions
Kilowatt-hour (kWh)
Source Unit- Scaling Ratio: One kilowatt-hour equals approximately 860,420.7 gram calories (1 kWh = 3,600,000 J ÷ 4.184 J/cal). Multiply kWh by ~860,420.7 to get calories.
- Water Heating Physics: Because 1 calorie raises 1 g of water by 1°C, 1 kWh of electricity (860,421 cal) can heat approximately 860 liters of water by 1°C (or 14.3 L from 20°C to 80°C).
Gram calorie (cal)
Target Unit- Water Heating Physics: Because 1 calorie raises 1 g of water by 1°C, 1 kWh of electricity (860,421 cal) can heat approximately 860 liters of water by 1°C (or 14.3 L from 20°C to 80°C).
- Thermodynamic Equivalency: Useful for evaluating electric heat pump coefficients of performance (COP) against fossil-fuel gas or oil heating values.
