Watt to BTU per Second Converter

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.

BTU per second (BTU/s) is a unit of power representing the rate of energy transfer of one British Thermal Unit per second. It's used in thermal engineering and HVAC applications, particularly in imperial unit systems.

BTU per second developed with the British Thermal Unit system and became important in thermal engineering and HVAC applications. It provided a power unit consistent with BTU energy measurements, particularly useful in heating and cooling system design.

BTU per second is used in HVAC engineering, thermal system design, and heating/cooling applications. It's standard in imperial unit thermal calculations, boiler specifications, and air conditioning system ratings.
