Mike McCune/Flickr. Definition: A British Thermal Unit (BTU) is the amount of heat energy needed to raise the temperature of one pound of water by one degree F. This is the standard measurement used to state the amount of energy that a fuel has as well as the amount of output of any heat generating device. You might be able to imagine it this way.
When used as a unit of power for heating and cooling systems, BTU per hour (BTU/h) is the correct unit, though this is often abbreviated to just BTU. 1  1 watt is approximately 3.41214 BTU/h. 2  1000 BTU/h is approximately 293.071 W.  1 horsepower is approximately 2544 BTU/h.
