What is a watt?
A watt is the SI derived unit of power, equal to one joule of energy per second (1 J/s). Named after Scottish engineer James Watt, whose steam-engine improvements powered the Industrial Revolution. The watt became the SI unit of power in 1960 and now measures everything from light bulbs to power plants.
Common uses of watts include: Light bulb and appliance ratings; Electronic device power consumption; Audio amplifier output; Scientific and electrical calculations.
What is a btu per hour?
A BTU per hour is a unit of power equal to about 0.293 watts, used to rate the heating and cooling capacity of HVAC equipment. Derived from the British thermal unit, BTU/h became the standard rating for air conditioners, furnaces, and heat pumps in the United States, where a '12,000 BTU' unit describes one ton of cooling.
Common uses of btus per hour include: Air conditioner cooling capacity; Furnace and heat-pump ratings; HVAC load calculations; Radiator and boiler output.
