Conversion formula

Forward
BTU = electronvolts × 1.5186e-22
Reverse
electronvolts = BTU × 6.5851e21

Example: 10 eV × 1.5186e-22 = 1.5186e-21 BTU.

About both units

Electronvolt

eV

The electronvolt equals 1.602 × 10⁻¹⁹ joules — the energy gained by an electron accelerated through 1 volt. It is the natural energy unit of atomic, nuclear and particle physics. Chemical bonds are a few eV; LHC protons reach 7 TeV = 7 × 10¹² eV.

Real-world: Silicon band gap: 1.12 eV. Hydrogen ionization: 13.6 eV. LHC proton: 7 TeV. Photon wavelength 500 nm = 2.5 eV.

British Thermal Unit

BTU

The British Thermal Unit equals approximately 1055 joules — the energy to raise 1 pound of water by 1 °F. Used for HVAC, heating, and air-conditioning capacity in the US. A 9000 BTU/h AC is a small room unit.

Real-world: Window AC: 5000–12,000 BTU/h. Central AC: 24,000–60,000 BTU/h. Home furnace: 60,000–100,000 BTU/h.

Tips & common mistakes

Quick tips

  • 1 eV ≈ 1.602 × 10⁻¹⁹ J.
  • Particle physics scales: eV → keV → MeV → GeV → TeV (1000× each).
  • Photon energy (eV) × wavelength (nm) ≈ 1240.

Avoid these

  • Confusing eV with V (volt) — eV is energy, V is electric potential.
  • Mixing scales: treating MeV as twice eV — it's a million times larger.
  • Using eV for macroscopic energy — unwieldy numbers.

Frequently asked questions

How many BTU in a electronvolt?
