What is Watt?

The watt is the SI unit of power, named after Scottish inventor James Watt. One watt equals one joule of energy per second. Household LED bulbs use about 7 to 12 watts, a microwave oven uses 500 to 1,000 watts, and a hair dryer uses about 1,200 watts. Electricity bills are based on watt-hours, the product of power consumption in watts and time of use.

What is BTU per hour?

BTU per hour is a unit of power used primarily in the American HVAC industry for rating heating and cooling capacity. Residential air conditioners range from about 5,000 to 25,000 BTU/h, with 12,000 BTU/h equaling one ton of refrigeration. Gas furnaces and boilers are also rated in BTU/h. One BTU/h equals approximately 0.293 watts.
