kilowatt hour
- Definition: A kilowatt hour (kWh) is a unit of energy equivalent to one kilowatt (1 kW) of power used for one hour. It measures the amount of energy consumed or produced over time.
- Symbol: The symbol for kilowatt hour is kWh.
- Usage: Kilowatt hours are commonly used by electric utilities to calculate energy consumption in households and businesses. It is a standard unit for billing and energy management.
erg
- Definition: An erg is a unit of energy in the centimeter-gram-second (CGS) system, defined as the amount of work done when a force of one dyne is applied over a distance of one centimeter.
- Symbol: The symbol for erg is erg.
- Usage: Ergs are primarily used in physics and engineering contexts, particularly in fields that work with smaller scales of energy and force.
Origin of the kilowatt hour
- The kilowatt hour originated as a practical unit to measure electrical energy consumption. It was developed in the late 19th century as electricity began to be widely adopted for residential and commercial use. The unit allows consumers to understand their energy usage in a more relatable way, correlating it directly to time and power consumption.
Origin of the erg
- The erg was introduced in the late 19th century as part of the centimeter-gram-second system of units. It was derived from the forces and distances typical in mechanical systems at the time, making it a useful unit in physics and engineering to quantify work and energy in smaller scales.
