Btu (Th)/hour
Btu (th)/hour is a unit of power that measures the rate of energy transfer, specifically the amount of thermal energy in British thermal units (Btu) delivered or consumed per hour.
History/Origin
The Btu (th)/hour originated from the British thermal unit (Btu), a traditional unit of heat energy, and has been used primarily in the heating and energy industries to quantify thermal power rates. Its usage dates back to the early 20th century as a standard measure in thermal energy calculations.
Current Use
Today, Btu (th)/hour is used mainly in the heating, ventilation, and air conditioning (HVAC) industry, as well as in energy consumption and efficiency assessments, to specify thermal power rates of equipment and systems.
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.
