erg to Wh

erg

• Definition: An erg is a unit of energy or work in the centimeter-gram-second (CGS) system. It is defined as the amount of work done when a force of one dyne moves an object one centimeter.

• Symbol: The symbol for erg is “erg.”

• Usage: Ergs are primarily used in fields of physics and engineering, particularly in contexts where very small quantities of energy are involved. They are not commonly used in everyday applications.

watt hour

• Definition: A watt hour (Wh) is a unit of energy equivalent to one watt of power expended for one hour. It represents the amount of energy consumed or produced over time.

• Symbol: The symbol for watt hour is “Wh.”

• Usage: Watt hours are commonly used to measure electrical energy consumption, such as in household appliances or to quantify energy storage in batteries.

Origin of the erg

• The erg originated from the centimeter-gram-second system of units, which was developed in the 19th century. It was created to provide a practical unit for measuring small amounts of energy, especially in scientific and engineering contexts.

Origin of the watt hour

• The watt hour was introduced in the late 19th century as electrical engineering began to evolve. It was named after James Watt, whose work in developing the steam engine laid the groundwork for the measurement of energy in terms of electrical power.
