About Kilowatt-hour and Joule
Detailed information about both units of measurement.
Kilowatt-hour
- Definition
- One thousand watt-hours or 3.6 million joules. The standard unit for household electricity billing.
- SI / Standard Information
- SI-derived unit (kWh). 1 kWh = 3,600,000 J. The most common energy unit for residential and commercial electricity worldwide.
- Approximate Comparison
- One kWh is enough to power a refrigerator for a day or a TV for about 10 hours.
- Practical Applications
-
- Residential electricity billing
- EV battery capacity rating
- Appliance energy consumption labeling
- Solar system energy production
- Real-World Examples
-
- The average US home uses about 900 kWh per month
- A Tesla Model 3 has a 60-82 kWh battery
- Running a 1,000 W microwave for 1 hour uses 1 kWh
Joule
- Definition
- The SI unit of energy, defined as the work done by a force of 1 newton over a distance of 1 meter.
- SI / Standard Information
- SI-derived unit (J). Named after James Prescott Joule. 1 J = 1 N·m = 1 kg·m²/s². Fundamental unit in physics and engineering.
- Approximate Comparison
- One joule is roughly the energy needed to lift a small apple one meter off the ground.
- Practical Applications
-
- Physics and scientific research
- Mechanical and electrical engineering
- Food energy measurement (as kJ)
- Battery and energy storage rating
- Real-World Examples
-
- Lifting a small apple 1 meter uses about 1 joule
- A 60W light bulb uses 60 joules per second
- A typical lightning bolt contains about 1 billion joules
