About These Units
Erg (erg)
An erg is the CGS (centimeter-gram-second) unit of energy equal to 10⁻⁷ joules or 1 dyne-centimeter. Ergs appear in older scientific literature and some astronomical calculations. One joule equals 10 million ergs. Rarely used in modern applications.
Watt-hour (Wh)
A watt-hour (Wh) is the energy of one watt sustained for one hour, equal to 3,600 joules. Watt-hours measure battery capacity (smartphone: 10-15 Wh, laptop: 50-100 Wh) and small appliance energy use. One Wh equals 3.6 kilojoules.
