It is a measurement of heat energy or the output of a heating or cooling device. A British Thermal Unit is the amount of energy needed to raise or lower the temperature of one pound of water by one degree F.

BTU is short for British Thermal Unit. 1 BTU is the heat required to raise 1 lb of water by 1 degF. So it is a quantity of heat, which is equivalent to a quantity of energy, in fact 1 BTu = 1.055 kilojoules, so 1 BTU/second = 1.055 kilowatts. This is called the mechanical equivalent of heat.

BTU is not a unit in the metric system.

BTU = British Thermal Units. It is an obsolete unit of energy. The unit of energy in the metric system is the 'Joule'. 1 BTU is approximately 1055 Joules.

Are MBH and BTU the same?

BTU means" british thermal unit " and is a measure of energy like kWh or Joules. BTU is often used in air conditioning.

What does BTHhr mean?

I think you may mean BTU/hr. BTU means British Thermal Unit which is defined as the heat to raise 1 lb of water by 1 degF, so BTU/hr would mean so many BTU's per hour, which is a rate of energy flow. Home heating boilers are often rated in BTU/hr though they may more recently be rated in Kilowatts. 100,000 BTU/hr = 29.3 Kw.
