NationMaster - Encyclopedia: Board of Trade Unit

The Board of Trade Unit or B.O.T.U. is a non-SI unit of electrical energy, defined by a former department of the UK government. It is the same as the kilowatt-hour (kWh), which is the amount of energy consumed by a one kilowatt appliance in one hour.

One B.O.T.U. or kWh = 3.6 � 10⁶ joule.

The B.O.T.U. should not be confused with the British thermal unit or BTU, which is a much smaller quantity of thermal energy.

British thermal unit - Wikipedia, the free encyclopedia (322 words)
	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 should not be confused with the Board of Trade Unit (B.O.T.U.), which is a much larger quantity of energy.
