BTU per Hour to Watt 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 watt (W) is the SI unit of power, defined as one joule per second. Named after Scottish inventor James Watt, it represents the rate of energy transfer and is fundamental to all power measurements in the International System of Units.

The watt was named after James Watt in 1882 and became the SI unit of power in 1960. It replaced various earlier power units and provided a unified measure based on the fundamental relationship between energy and time, becoming universal in scientific and technical applications.

Watts are universally used for all power measurements, from small electronic devices to large machinery. They're fundamental in electrical engineering, physics, energy efficiency ratings, and form the basis for all other power unit measurements.
