	British thermal unit - Wikipedia, the free encyclopedia
		The British thermal unit (BTU or Btu) is a unit of energy used in the United States.
		A Btu is defined as the amount of heat required to raise the temperature of one pound avoirdupois of water by one degree Fahrenheit.
		The BTU is a unit of energy, and therefore not a unit of power, so while power can be measured in BTU-per-hour (BTU/h), it cannot be measured in BTU any more than it can be measured in milliseconds.

		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).
