Convert attowatt to kilocalorie (th)/hour
Enter a value below to convert attowatt [aW] to kilocalorie (th)/hour [kcal(th)/h]. Reverse conversion: Convert kilocalorie (th)/hour to attowatt.
1 aW = 8.6042e-19 kcal(th)/h. To convert attowatt to kilocalorie (th)/hour, multiply the value by 8.6042e-19; to go the other way, divide by it (1 kcal(th)/h = 1.1622e+18 aW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Attowatt: Definition and Use
An attowatt (aW) is a unit of power equal to 10^-18 watts, representing an extremely small amount of power.
History/Origin
The attowatt is part of the SI prefix system introduced to denote very small quantities, with 'atto-' representing 10^-18. It has been used mainly in scientific contexts to measure minuscule power levels.
Current Use
The attowatt is rarely used in practical applications but may be referenced in scientific research involving extremely low power measurements, such as in quantum physics or nanotechnology.
Kilocalorie (Th)/hour: Definition and Use
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.
