Convert calorie (th)/hour to attojoule/second
Please provide values below to convert calorie (th)/hour [cal(th)/h] to attojoule/second [aJ/s], or Convert attojoule/second to calorie (th)/hour.
1 cal(th)/h = 1.1622e+18 aJ/s. To convert calorie (th)/hour to attojoule/second, multiply the value by 1.1622e+18; to go the other way, divide by it (1 aJ/s = 8.6042e-19 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+18 aJ/s
- 1 aJ/s = 8.6042e-19 cal(th)/h
- 10 cal(th)/h = 1.1622e+19 aJ/s
- 100 cal(th)/h = 1.1622e+20 aJ/s
How to Convert Calorie (Th)/hour to Attojoule/second
1 cal(th)/h = 1.16222222e+18 aJ/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.
Attojoule/second
An attojoule per second (aJ/s) is a unit of power representing the rate of energy transfer or conversion of one attojoule (10^-18 joules) per second.
History/Origin
The attojoule is a relatively recent SI prefix introduced to measure extremely small quantities of energy, and its use in power units like aJ/s has emerged with advancements in nanotechnology and quantum physics, though it remains a specialized unit with limited historical usage.
Current Use
The aJ/s is used in scientific research involving extremely low power measurements, such as in quantum physics, nanotechnology, and energy transfer studies at the atomic or molecular scale.
