Millijoule/second

A millijoule per second (mJ/s) is a unit of power equivalent to one millijoule of energy transferred or converted every second.

History/Origin

The unit derives from the joule, the SI unit of energy, and the second, the SI unit of time. It has been used in contexts requiring small power measurements, especially in scientific and engineering applications, with the millijoule being a submultiple of the joule.

Current Use

Millijoule per second is used to measure small power levels in scientific experiments, electronics, and other fields where precise, small-scale power measurement is necessary, often within the context of energy transfer or consumption rates.


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.
