Please provide values below to convert kilocalorie (th)/second [kcal(th)/s] to petajoule/second [PJ/s], or Convert petajoule/second to kilocalorie (th)/second.
How to Convert Kilocalorie (Th)/second to Petajoule/second
1 kcal(th)/s = 4.184e-12 PJ/s
Example: convert 15 kcal(th)/s to PJ/s:
15 kcal(th)/s = 15 × 4.184e-12 PJ/s = 6.276e-11 PJ/s

Kilocalorie (Th)/second
A kilocalorie (th)/second (kcal(th)/s) is a unit of power representing the rate at which energy in kilocalories per second is transferred or converted.
History/Origin
The kilocalorie (th) is a traditional unit of energy used primarily in nutrition and thermodynamics, with 'th' indicating the thermochemical definition. Its use in power measurements, such as kcal(th)/s, is less common and primarily for specialized scientific contexts.
Current Use
The unit kcal(th)/s is rarely used in modern practice; power is more commonly expressed in watts. When used, it typically appears in scientific research involving energy transfer rates in thermochemical processes or specialized engineering applications.
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.
