	While the joule is the [[SI]] base unit for energy, when speaking in real-world terms, we often use the [[kilowatt-hour]] (kWh) instead. This is due to the fact that a joule is an extremely small amount of energy. To put how small a joule is into perspective, a [[liter]] of [[gasoline]] has 31,536,000 joules of energy in it. Using a single 100 W incandescent light bulb for ten hours (0.1 kW x 10 hrs = 1 kWh) would take 3,600,000 joules.
