Ergs (erg) to British thermal units (BTU) 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 Though largely superseded by the joule in modern science, the erg persists in astrophysics — stellar luminosities and gamma-ray burst energies are sometimes expressed in ergs — and in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.
British thermal units
The British thermal unit (BTU) is a unit of energy approximately equal to 1,055.06 joules, defined as the energy required to raise the temperature of one pound of water by one degree Fahrenheit. It remains the standard unit for heating and cooling capacity in HVAC systems in the United States: air conditioners and furnaces are rated in BTU/hour. A typical residential air conditioner is rated at 5,000–24,000 BTU/h. One BTU equals approximately 0.000293 kWh.
