  British thermal unit - Wikipedia, the free encyclopedia
The British thermal unit (BTU or Btu) is a non-metric unit of energy, used in the United States and, to a lesser extent, the UK (where it is generally only used for heating systems).
A BTU is defined as the amount of heat required to raise the temperature of one pound avoirdupois of water by one degree Fahrenheit; specifying the temperature range over which this happens leads to a number of slightly different BTU values, varying over a range of about 0.5%:
The BTU is often used to describe the heat value of fuels, or the heating and cooling power of a system (such as a barbecue grill).

 BTU - Basic Transmission Unit, British Thermal Unit
One BTU is the amount of heat required to raise the temperature of one pound of water one degree Fahrenheit.
One Btu is the amount of heat needed to raise the temperature of one pound of water 1°F. To get a rough idea of how much heat energy this is, the heat given off by burning one wooden kitchen match is approximately one Btu.
Specifically, one BTU is the amount of energy required to raise the temperature of one pound of water one degree Fahrenheit.

The British Thermal Unit (BTU) was defined as the amount of heat necessary to raise the temperature of one pound of water one degree Fahrenheit from 58.5 to 59.5 degrees Fahrenheit.
It wasn't until the late 1700's and early 1800's that heat was defined as a form of energy which could be measured and related to other forms of energy.
However, by that time, the BTU was ingrained in common use and is still in common use to this day.
