SEER Defined, Explained, Calculated Air Conditioning SEER Energy Efficiency Ratings Explained - HVAC Dictionary Definition of BTU-British Thermal Unit. A BTU is a measure of heat energy, or the amount of heat given off when a unit of fuel is consumed. One BTU is the amount of heat energy we need to raise the temperature of one pound of water by one degree Fahrenheit. One BTU also is defined as 252 heat calories (this is not the same as food calories). When talking about air conditioners or heaters, we talk about the A/C unit's BTUh capacity-the number of BTUs of cooling (lowering rather than raising temperature) it can produce in an hour of running.

- A standard unit of measurement used to denote both the amount of heat energy in fuels and the ability of appliances and air conditioning systems to produce heating or cooling. A BTU is the amount of heat required to increase the temperature of a pint of water (which weighs exactly 16 ounces) by one degree Fahrenheit. Since BTUs are measurements of energy consumption, they can be converted directly to kilowatt-hours (3412 BTUs = 1 kWh) or joules (1 BTU = 1,055.06 joules).

- {Sigh} I hate English units. A BTU is defined as the amount of heat required to raise the temperature of 1 lb of water by 1 deg F. The basic relation is Q = mcdT Heat = mass * … heat capacity * change in temperature.A gallon of water weighs about 8 lb, so you're talking about 500,000 gal * 8 lb/gal = 4 million pounds. BTU is defined as the amount of heat required to raise the temperature of 1 lb of water by 1 deg F. The basic relation is Q = mcdT Heat = mass * … heat capacity * change in temperature.

British thermal unit The British thermal unit (BTU or Btu) is a traditional unit of work equal to about 1055 joules. It is the amount of work needed to raise the temperature of one pound of water by one degree Fahrenheit (Physical analogue: one four-inch wooden kitchen match consumed completely generates approximately 1 BTU).efinitions of the BTU based on different water temperatures can therefore vary by up to 0.5%. A BTU can be approximated as the heat produced by burning a single wooden kitchen match or as the amount of energy it takes to lift a one-pound weight 778 feet (237 m).

How is Energy Measured? A British Thermal Unit (Btu) is a measure of energy content, usually used to describe the energy content of fuels. Because a Btu is so small, energy is usually measured in millions of Btus. 1 Btu = the amount of energy required to increase the temperature of one pound of water (which is equivalent to one pint) by one degree Fahrenheit. This is roughly the heat produced from burning one match. 1,000 Btu = four-fifths of the energy contained in a peanut butter and jelly sandwich. 100,000 Btu = one therm, such as what you would find on your gas bill.

- BTU stands for 'British Thermal Unit' and is a measurement of energy. One BTU is approximately the amount of energy required to heat one pound of water by 1° Fahrenheit - about the same amount of energy produced by a single 4-inch kitchen match that's been burned from one end to the other. BTU’s are commonly used to measure and compare the heat output of different hot water radiators.
