Convert petawatt to kilocalorie (th)/hour
Please provide values below to convert petawatt [PW] to kilocalorie (th)/hour [kcal(th)/h], or Convert kilocalorie (th)/hour to petawatt.
1 PW = 8.6042e+14 kcal(th)/h. To convert petawatt to kilocalorie (th)/hour, multiply the value by 8.6042e+14; to go the other way, divide by it (1 kcal(th)/h = 1.1622e-15 PW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 PW = 8.6042e+14 kcal(th)/h
- 1 kcal(th)/h = 1.1622e-15 PW
- 10 PW = 8.6042e+15 kcal(th)/h
- 100 PW = 8.6042e+16 kcal(th)/h
How to Convert Petawatt to Kilocalorie (Th)/hour
1 PW = 860420651740766 kcal(th)/h

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.
Kilocalorie (Th)/hour
A kilocalorie (th)/hour (kcal(th)/h) is a unit of power representing the rate at which energy in kilocalories per hour is transferred or converted.
History/Origin
The kilocalorie, often used in nutrition and energy measurement, has been adapted into various units including the thermochemical kilocalorie (kcal(th)). Its use in power measurement, such as kcal(th)/h, is primarily for specialized scientific and engineering applications, integrating energy units with time to express power.
Current Use
The kcal(th)/h unit is used in contexts requiring the measurement of energy transfer rates in thermochemical terms, such as in thermal engineering, calorimetry, and energy efficiency assessments where energy flow is expressed in kilocalories per hour.
