BTU Calculator
A BTU or British thermal unit is a unit of energy. A BTU describes the energy content or heat value of fuels. The amount of energy that is needed to either cool or heat one pound of liquid water one degree Fahrenheit at a constant pressure of one atmosphere. In recent years the scientific industry contexts is more commonly replacing this unit of measure by the SI unit of energy, the joule.
Several BTU definitions exist, based on different water temperatures. A BTU is approximately the amount of heat produced when burning a single wooden match, or as the amount of energy required to lift one pound weight 778 feet. BTU is most generally used to measure the amount of power in several industries including agricultural, power, steam generation, and heating ventilation air conditioning (HVAC). In the agricultural energy production a BPU is used to measure energy by the kilogram (BTU/kg). For natural, or LP gas, a BPU is used to measure the volume of energy content. Typically on standard cubic foot of typical natural gas measures approximately;y 1030BTU, depending on the quality. When used in HVAC industry a BPU measures power, referred to as BTU per hour (BTU/h), although commonly it is abbreviated to BTU. One horsepower is approximately 2554 BTU/h. This conversion calculator is provided to estimate the amount of BTU needed for the heating and cooling requirements of specific areas by converting BTU’s into BTU/h.
