Understanding Kilowatt-hour and Joule
Kilowatt-hour (kWh)
The kilowatt-hour is a unit of energy in the Electrical system.
• Standard unit for electrical energy
• 1 kWh = energy of 1000W for 1 hour
• Used for electricity billing worldwide
• Typical home uses 10-30 kWh/day
Joule (J)
The joule is a unit of energy in the SI system.
• Fundamental unit in physics
• Used in all scientific publications
• Standard for energy equations
• Basis for all other energy units
Electrical to SI Conversion
You are converting from a electrical unit to a si unit. This conversion is commonly needed when:
- Comparing nutritional information with scientific data
- Calculating electricity costs for different energy sources
- Converting physics laboratory measurements
- Working with international engineering specifications
- Translating between different measurement traditions
Practical Examples
Everyday Examples
- • 1 kWh (electricity unit) = 3.6 million joules
- • LED bulb (10W for 10 hours) = 0.1 kWh = 360,000 joules
- • Electric car (15 kWh/100km) = 54 million joules/100km
