Petawatt
A petawatt (PW) is a unit of power equal to 10^15 watts, used to measure extremely high power levels.
History/Origin
The petawatt was introduced in the 1980s as part of the SI prefixes to describe ultra-high power outputs, particularly in laser physics and astrophysics research.
Current Use
Petawatts are primarily used in scientific research involving high-intensity lasers, astrophysics, and nuclear physics to quantify extremely large power outputs.
Erg/second
The erg/second (erg/s) is a unit of power representing the rate of energy transfer or conversion, where one erg per second equals the transfer of one erg of energy per second.
History/Origin
The erg is an older CGS (centimeter-gram-second) unit of energy, introduced in the early 20th century for scientific calculations. The erg/second was used in physics to quantify power in contexts where the CGS system was prevalent, especially in astrophysics and theoretical physics.
Current Use
Today, the erg/second is rarely used outside specialized scientific fields; the SI unit watt (W) is preferred for measuring power. However, erg/s may still be encountered in historical data, astrophysics, or when working with CGS-based calculations.
