How to Convert Calorie (Th)/second to Petajoule/second
1 cal(th)/s = 4.184e-12 PJ/s
Example: convert 15 cal(th)/s to PJ/s:
15 cal(th)/s = 15 × 4.184e-12 PJ/s = 6.276e-11 PJ/s

Calorie (Th)/second
Calorie (th)/second (cal(th)/s) is a unit of power representing the rate at which thermal calories are transferred or converted per second.
History/Origin
The calorie (th), or thermochemical calorie, was historically used to quantify energy in thermodynamics and nutrition. Its use in power measurement, such as cal(th)/s, emerged in scientific contexts to express thermal energy transfer rates before the adoption of the watt as the standard SI unit.
Current Use
Today, cal(th)/s is rarely used in scientific practice, having been largely replaced by watts (W). It may still appear in specialized fields or historical references related to thermal energy transfer rates.
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.
