Convert attowatt to Btu (IT)/hour
Please provide values below to convert attowatt [aW] to Btu (IT)/hour [Btu/h], or Convert Btu (IT)/hour to attowatt.
1 aW = 3.4121e-18 Btu/h. To convert attowatt to Btu (IT)/hour, multiply the value by 3.4121e-18; to go the other way, divide by it (1 Btu/h = 2.9307e+17 aW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 aW = 3.4121e-18 Btu/h
- 1 Btu/h = 2.9307e+17 aW
- 10 aW = 3.4121e-17 Btu/h
- 100 aW = 3.4121e-16 Btu/h
How to Convert Attowatt to Btu (It)/hour
1 aW = 3.41214163513308e-18 Btu/h

Attowatt
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.
Btu (It)/hour
Btu (IT)/hour (Btu/h) is a unit of power that measures the rate of energy transfer, specifically the amount of British thermal units (IT) transferred per hour.
History/Origin
The Btu (IT) originated from the British thermal unit used in the United States and was standardized for industrial and engineering purposes. The per-hour notation became common in applications requiring power measurement, especially in heating and cooling systems.
Current Use
Btu/h is widely used in heating, ventilation, and air conditioning (HVAC) industries to specify the capacity of heating and cooling equipment, as well as in energy analysis and thermodynamics.
