Conversion Formula
To convert kilowatt-hours (kwh) to calories (cal), you multiply the amount of kwh by the calories contained in one kwh. The formula is:
cal = kwh × 850,400
Why does this work? Because one kilowatt-hour is the amount of energy equivalent to 3.6 million joules, and 1 calorie equals approximately 4.184 joules, so converting joules to calories gives 1 kwh = 850,400 cal.
Example calculation for 740 kwh:
- Start with 740 kwh
- Multiply by 850,400 cal/kwh: 740 × 850,400 = 629,040,000 cal
- So, 740 kwh equals 629,040,000 calories
Conversion Example
- Convert 500 kwh to cal:
- 500 × 850,400 = 425,200,000 cal
- This means 500 kwh equals 425,200,000 calories
- Convert 825 kwh to cal:
- 825 × 850,400 = 701,580,000 cal
- The result shows 825 kwh equals 701,580,000 calories
- Convert 100 kwh to cal:
- 100 × 850,400 = 85,040,000 cal
- Meaning 100 kwh is 85,040,000 calories
- Convert 620 kwh to cal:
- 620 × 850,400 = 527,248,000 cal
- So, 620 kwh equals 527,248,000 calories

Conversion Definitions
kwh: Kilowatt-hour (kwh) is a unit of energy equal to one kilowatt (1,000 watts) of power used for one hour. It measures electrical energy consumption or generation and is commonly used for billing electricity usage in homes and industries.
cal: The calorie (cal) is a unit of energy mainly used to quantify heat or food energy. One calorie is the amount of heat needed to raise one gram of water by one degree Celsius at one atmosphere pressure.
Conversion FAQs
Why is 1 kwh equal to 850,400 calories?
Because 1 kwh equals 3.6 million joules, and since 1 calorie equals about 4.184 joules, dividing 3,600,000 by 4.184 gives approximately 850,400 calories. This conversion uses the relationship between joules and calories as energy units.
Can I convert kwh to food calories directly?
No, the calorie in food (often written as Calorie with capital C) is actually a kilocalorie, which equals 1,000 small calories. So, converting kwh to food calories needs an additional step multiplying by 1,000 to get dietary Calories.
Does converting kwh to calories depend on temperature?
No, the conversion between kwh and calories is based on fixed physical constants relating energy units. Temperature changes don’t affect these conversions since they measure energy quantity, not conditions of the system.
Why use calories instead of joules for energy?
Calories are often used in contexts like food energy or heat, which can make it easier for people to relate to energy content. Joules are the SI unit, but calories can be more intuitive in some fields, especially nutrition and thermodynamics.
Is it possible to convert kwh to calories without a calculator?
Yes, if you know the conversion factor of 1 kwh = 850,400 calories, you can multiply manually. But because numbers get large quickly, using a calculator or tool is recommended for accuracy and speed.
