How to Convert Electronvolts to BTU

The electronvolt and british thermal unit are both units of energy. By definition, 1 british thermal unit equals exactly 6.5851406782e21 electronvolts. This means to convert electronvolts to btu, you divide by 6.5851406782e21.

Formula

btu = electronvolts ÷ 6.5851406782e21

Step-by-Step Example

Convert 5 eV to btu:

1
Convert 5 eV to btu

We need to convert electronvolts to btu

2
Apply the formula

Since 1 BTU = 6.5851406782e21 eV, divide by 6.5851406782e21

5 ÷ 6.5851406782e21 = 7.5928522174e-22

Answer

5 eV = 7.5928522174e-22 BTU

About These Units

Electronvolt (eV)

An electronvolt (eV) is the energy gained by an electron accelerated through 1 volt potential difference, equal to 1.602×10⁻¹⁹ joules. Electronvolts measure atomic and molecular energies, photon energy (visible light: 1.6-3.3 eV), and particle physics. X-rays range from 100 eV to 100 keV.

British Thermal Unit (BTU)

A British Thermal Unit (BTU) is the energy needed to raise 1 pound of water by 1°F, equal to approximately 1,055 joules. BTUs measure heating/cooling capacity (AC units: 5,000-25,000 BTU), fuel energy content, and HVAC systems. One BTU equals 252 calories.
