About the units
British thermal unit (BTU)
The International Table BTU, 1,055.05585262 J — roughly the energy to heat one pound of water by 1 °F. Furnace and AC capacities are rated in BTU (per hour). One British thermal unit equals 1,055.055853 joules (J).
Electronvolt (eV)
The energy an electron gains across one volt: exactly 1.602176634 × 10⁻¹⁹ J. One electronvolt equals 1.602176634×10⁻¹⁹ joules (J).
Frequently asked questions
How many electronvolts are in one British thermal unit?
There are 6.585140678×10²¹ electronvolts in one British thermal unit, and this value is exact by definition.
How do I convert British thermal units to electronvolts?
Multiply the number of British thermal units by 6.585140678×10²¹. For example, 10 BTU × 6.585140678×10²¹ = 6.585140678×10²² eV.
How many British thermal units are in one electronvolt?
One electronvolt equals 1.518570443×10⁻²² British thermal units. That is the reverse factor, 1 ÷ 6.585140678×10²¹.
What is 10 British thermal units in electronvolts?
10 BTU = 6.585140678×10²² eV.
