Convert erg/second to petajoule/second
Please provide values below to convert erg/second [erg/s] to petajoule/second [PJ/s], or Convert petajoule/second to erg/second.
How to Convert Erg/second to Petajoule/second
1 erg/s = 1e-22 PJ/s
Example: convert 15 erg/s to PJ/s:
15 erg/s = 15 × 1e-22 PJ/s = 1.5e-21 PJ/s

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.
Petajoule/second
A petajoule per second (PJ/s) is a unit of power representing the transfer or conversion of one petajoule of energy every second.
History/Origin
The petajoule (PJ) is a metric unit of energy introduced as part of the International System of Units (SI) to measure large quantities of energy. The concept of power in terms of energy per unit time has been fundamental in physics, with the watt (W) as the SI base unit. The petajoule per second emerged as a large-scale unit for high-energy power measurements, especially in fields like energy production and scientific research.
Current Use
Petajoule per second is used in scientific and engineering contexts to quantify extremely high power levels, such as in nuclear energy, large-scale power generation, and astrophysics. It is also used in theoretical and large-scale energy calculations where conventional units like watts are insufficient.
