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.
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.
