How to Convert Electronvolts to British Thermal Units

To convert an electronvolt measurement to a british thermal unit measurement, multiply the energy by the conversion ratio.

Since one electronvolt is equal to 1.5186E-22 british thermal units, you can use this simple formula to convert:

british thermal units = electronvolts × 1.5186E-22

The energy in british thermal units is equal to the electronvolts multiplied by 1.5186E-22.

For example, here's how to convert 5.0E+21 electronvolts to british thermal units using the formula above.
5.0E+21 eV = (5.0E+21 × 1.5186E-22) = 0.759285 BTU

Electronvolts and british thermal units are both units used to measure energy. Keep reading to learn more about each unit of measure.


The electronvolt is a unit of energy used in physics, most commonly in electrostatic particle accelerator sciences.

Electronvolts can be abbreviated as eV; for example, 1 electronvolt can be written as 1 eV.

Energy in electronvolts can be expressed using the following formula: E = qV

The energy E in electronvolts is equal to the electric charge q in elementary charge times the potential difference V in volts.

British Thermal Units

British thermal units are a measure of heat energy. Specifically, one british thermal unit is equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit. They are often used as a way to rate the energy heat producing appliances such furnaces, and to price heating fuels such as natural gas.

The british thermal unit is a US customary unit of energy. British thermal units can be abbreviated as BTU; for example, 1 british thermal unit can be written as 1 BTU.
