Convert calorie (th)/hour to petajoule/second
Please provide values below to convert calorie (th)/hour [cal(th)/h] to petajoule/second [PJ/s], or Convert petajoule/second to calorie (th)/hour.
1 cal(th)/h = 1.1622e-15 PJ/s. To convert calorie (th)/hour to petajoule/second, multiply the value by 1.1622e-15; to go the other way, divide by it (1 PJ/s = 8.6042e+14 cal(th)/h). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 cal(th)/h = 1.1622e-15 PJ/s
- 1 PJ/s = 8.6042e+14 cal(th)/h
- 10 cal(th)/h = 1.1622e-14 PJ/s
- 100 cal(th)/h = 1.1622e-13 PJ/s
How to Convert Calorie (Th)/hour to Petajoule/second
1 cal(th)/h = 1.16222222e-15 PJ/s
Example: convert 15 cal(th)/h to PJ/s:
15 cal(th)/h = 15 × 1.16222222e-15 PJ/s = 1.74333333e-14 PJ/s

Calorie (Th)/hour
Calorie per hour (cal(th)/h) is a unit of power representing the amount of heat energy in calories transferred or used per hour.
History/Origin
The calorie, originally defined as the amount of heat needed to raise the temperature of 1 gram of water by 1°C, has been used in various contexts including nutrition and physics. The 'th' denotes the thermochemical calorie, an older standard. The unit cal(th)/h has been used historically in thermodynamics and heat transfer measurements.
Current Use
Today, cal(th)/h is rarely used in modern scientific contexts, having been largely replaced by SI units like watts. However, it may still appear in legacy systems or specialized fields involving heat transfer 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.
Frequently Asked Questions
What is 1 calorie (th)/hour in petajoule/second?
1 calorie (th)/hour (cal(th)/h) = 1.1622e-15 petajoule/second (PJ/s).
How do you convert calorie (th)/hour to petajoule/second?
