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.
What is a BTU. A BTU, short for British Thermal Unit, is a basic measure of thermal (heat) energy. One BTU is the amount of energy needed to heat one pound of water one degree Fahrenheit, measured at its heaviest point. unit of measure called the MMBTU is the equivalent of a million BTU's. Few man-made objects can generate this level of thermal energy, however. When shopping for heating or cooling systems, keep in mind that even the smallest window-mounted air conditioner or space heater can produce thousands of BTU's.
