BTU per Hour to Milliwatt Converter

BTU per hour (BTU/h) is a unit of power representing the rate of energy transfer of one British Thermal Unit per hour. It's widely used in HVAC applications and provides a practical scale for heating and cooling system ratings.

BTU per hour became the standard power unit for HVAC systems and thermal equipment. It provided an appropriate scale for heating and cooling applications, becoming universally adopted in the HVAC industry and building energy systems.

BTU per hour is extensively used in HVAC systems, heating and cooling equipment ratings, building energy calculations, and thermal system specifications. It's standard for furnace ratings, air conditioner capacity, and building thermal load calculations.

A milliwatt (mW) is a unit of power equal to one thousandth of a watt (0.001 W). It represents very small amounts of power typically found in electronic devices, sensors, and low-power applications.

The milliwatt became important with the development of electronics and semiconductor technology. It provided an appropriate scale for describing the power consumption of transistors, integrated circuits, and electronic devices where power efficiency was crucial.

Milliwatts are used in electronics for component power ratings, laser output specifications, radio frequency applications, and low-power device design. They're standard for electronic component specifications, sensor power consumption, and precision instruments.
