The Uses of BTU (IT)/Hour units to Watts Conversion
BTU (IT) per hour is the standard unit printed on most furnace, heater, and HVAC nameplates, so this conversion is most useful when comparing against an electrical power draw figure given in watts.
Reading Standard Appliance Heat Output Specs
HVAC technicians who calculate an appliance's electrical draw in watts convert its rated heat output, given in BTU (IT) per hour, into watts to confirm the two figures are consistent.
Sizing Small Space Heating Equipment
Facility engineers who size small heating elements rated in watts convert a room's required heat input, specified in BTU (IT) per hour, into watts to select appropriately rated equipment.
Comparing International Appliance Ratings to US Watt Labels
Appliance importers who compare a product's BTU (IT) per hour rating from an international spec sheet convert the figure into watts to match US-style appliance labeling conventions.

Frequently Asked Questions
How many watts are in 1 btu (it)/hour?
1 btu (it)/hour equals 0.293071 watts, a figure useful for anyone working at the standard HVAC and appliance heat output ratings scale.
How many btu (it)/hour units are in 1 watt?
1 watt equals approximately 3.41214 btu (it)/hours, which puts the size of a single watt into perspective against the btu (it)/hour.
Why would anyone convert BTU (IT) per hour to watts?
This comes up constantly in HVAC and appliance work, where heating equipment rated in BTU (IT) per hour needs to be compared against an electrical power draw figure tracked in watts.
Is this the same BTU used on most furnace and heater nameplates?
Yes. BTU (IT) per hour, based on the International Table British thermal unit, is the standard definition used on the vast majority of modern furnace, heater, and HVAC nameplates.
