Ergs (erg) to Kilowatt-hours (kW·h) Conversion
Ergs
The erg is a unit of energy in the CGS (centimetre-gram-second) system, equal to exactly 10⁻⁷ joules. The word derives from the Greek ergon (work). Though largely superseded by the joule in modern science, the erg persists in astrophysics — stellar luminosities and gamma-ray burst energies are sometimes expressed in ergs — and in classical physics texts. One erg is approximately the energy required to move a mosquito by 1 cm. The total energy released by the Sun per second is approximately 3.8 × 10³³ ergs.
Kilowatt-hours
The kilowatt-hour (kW·h) is a unit of energy equal to exactly 3,600,000 joules (3.6 MJ), defined as the energy consumed by a one-kilowatt device operating for one hour. It is the standard unit on electricity bills worldwide. A typical European household consumes approximately 3,500 kWh per year. One kWh powers a 100-watt bulb for 10 hours, charges an electric vehicle by approximately 5–8 km of driving range, or powers the average laptop for about 10 hours.
