Joule per Second to BTU per Second Converter

Joule per second (J/s) is a unit of power representing the rate of energy transfer of one joule per second. It's exactly equivalent to the watt and represents the fundamental definition of power as energy per unit time.

Joule per second represents the fundamental definition of power and was implicit in early thermodynamic studies. It became formalized with the development of the SI system and provides the direct relationship between energy (joules) and power (watts).

Joule per second is primarily used in educational contexts to illustrate the relationship between energy and power. In practical applications, it's equivalent to watts and is used in thermodynamic calculations and energy system analysis.

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.
