Btu To Fahrenheit Formula

The following formula is used to convert British Thermal Units (Btu) to Fahrenheit (°F).

°F = (Btu / 0.00029307107) + 32


  • °F is the temperature in Fahrenheit Btu is the energy in British Thermal Units

To calculate the temperature in Fahrenheit, divide the energy in British Thermal Units by 0.00029307107, then add 32 to the result.

What is a Btu To Fahrenheit?

A Btu (British Thermal Unit) to Fahrenheit is not a direct conversion as they measure different things. Btu is a unit of heat energy in the British Imperial system while Fahrenheit is a temperature scale used primarily in the United States. One Btu is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. So, they are related in the sense that Btu measures the energy required to change temperatures as measured in degrees Fahrenheit, but you cannot convert Btu to Fahrenheit or vice versa.
