Calories (cal) to Ergs (erg) Conversion
Calories
The calorie (cal) is a unit of energy equal to exactly 4.184 joules, defined as the energy required to raise the temperature of one gram of water by one degree Celsius at 15 °C. This is the thermochemical calorie — distinct from the food calorie (written as Cal or kcal), which is 1,000 times larger. The calorie originated in 19th-century thermodynamics before the joule was established as the SI standard, and persists in chemistry, biology, and food science.
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 Though largely superseded by the joule in modern science, the erg persists in astrophysics — stellar luminosities and gamma-ray burst energies are sometimes expressed in ergs — and in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.
