Convert degree of Fahrenheit to btu?

Answer 1

Degrees Fahrenheit are a unit of temperature and British Thermal Units are units of heat; in physics, temperature and heat are not the same thing (although they are synonymous in normal English usage). To explain, the heat content of an object depends upon both the temperature and the heat capacity of that object, so for example, one liter of water has only half the heat capacity of two liters of water; even if your one liter container is at exactly the same temperature as the two liter container, it still has only half the heat content as measured in BTUs. So, since these units do not measure the same thing, they cannot be converted into eachother.
