Ergs

Definition

An erg is a CGS (centimeter-gram-second) unit of energy equal to 10⁻⁷ joules. It represents the work done by a force of one dyne over a distance of one centimeter.

History

The erg was the standard energy unit in the CGS system, widely used in physics before the SI system gained dominance. It was introduced in the mid-19th century alongside other CGS mechanical units.

Current use

Ergs are still used in astrophysics and some branches of physics, particularly for describing stellar energy output, supernova energies, and spectroscopic measurements in legacy literature.

British Thermal Units (BTU)

Definition

A British Thermal Unit (BTU) is an imperial unit of energy defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It equals approximately 1,055.06 joules.

History

The BTU originated in the British imperial measurement system in the 19th century. Despite the global shift toward metric units, it remains entrenched in US, UK, and Canadian HVAC and energy industries.

Current use

BTUs are the standard unit for rating heating and cooling equipment (furnaces, air conditioners), measuring natural gas energy content, and comparing fuel efficiencies in North America.
