Conversion Formula
The formula to convert kilowatt-hours (kwh) into calories (cal) uses the fact that 1 kwh equals 860,420 calories. This conversion works because a kilowatt-hour measures electrical energy, while calories measure heat energy. 1 watt = 1 joule per second, and 1 calorie equals approximately 4.184 joules.
So to convert:
Calories (cal) = Kilowatt-hours (kwh) × 860,420
For example, converting 740 kwh to calories:
- Multiply 740 by 860,420
- 740 × 860,420 = 636,710,800 calories
- This result shows how many calories of energy are equivalent to 740 kwh
Conversion Example
- Convert 500 kwh to calories:
- Multiply 500 × 860,420
- Result: 430,210,000 calories
- This means 500 kwh equals about 430 million calories
- Convert 123.5 kwh to calories:
- Multiply 123.5 × 860,420
- Result: 106,270,870 calories
- This shows the energy equivalence for 123.5 kwh
- Convert 850 kwh to calories:
- 850 × 860,420 = 731,357,000 calories
- So, 850 kwh equals over 731 million calories
- Convert 60 kwh to calories:
- 60 × 860,420 = 51,625,200 calories
- 60 kwh energy equals about 51.6 million calories

Conversion Definitions
kwh: A kilowatt-hour (kwh) is a unit of energy representing the consumption of one thousand watts over the period of one hour. It is commonly used by electric utilities to measure electricity usage, showing how much power is used over time.
cal: The calorie (cal) is a unit of energy used to quantify heat. It is defined as the amount of heat needed to raise the temperature of one gram of water by one degree Celsius. Calories are commonly used in food energy and thermodynamics.
Conversion FAQs
Why is the conversion factor between kwh and calories so large?
The calorie is a much smaller unit of energy compared to a kilowatt-hour. Since 1 kwh equals 3.6 million joules and 1 calorie is about 4.184 joules, this results in a large number of calories per kwh, causing the conversion factor to be in the hundreds of thousands.
Can I use this conversion to compare electric energy with thermal energy?
Yes, since both kwh and calories measure energy, the conversion lets you express electric energy as heat energy. However, practical applications depend on efficiency and conversion losses when turning electrical energy into heat.
Is the calorie used here the same as the dietary Calorie?
No, the calorie in this conversion is the small calorie (cal), which is different from the dietary Calorie (kcal). One dietary Calorie equals 1,000 small calories. So 740 kwh in dietary Calories would be 631,044 kcal, dividing the result by 1,000.
Does this conversion consider energy losses in real appliances?
No, the conversion is purely theoretical between energy units. Real-world devices have inefficiencies, so the usable heat energy from 740 kwh might be less than the calculated calories.
Is the conversion formula always constant for any value of kwh?
Yes, the factor of 860,420 calories per kwh stays constant because it depends on fixed physical constants relating joules to calories and watts to joules per second.
