Conversion formula

Forward

electronvolts = therms × 6.5851e26

Reverse

therms = electronvolts × 1.5186e-27

Example: 10 thm × 6.5851e26 = 6.5851e27 eV.

About both units

From

Therm

thm

The therm equals 100,000 BTU or 105.5 megajoules. Used in US and UK natural-gas billing. A typical UK home uses 200–500 therms per year for heating.

Real-world: UK home heating: 200–500 therms/year. 1 therm = about $1.50 US (2024) or £1.00 UK.

Electronvolt

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.

Tips & common mistakes

Quick tips

1 therm = 100,000 BTU = 105.5 MJ = 29.3 kWh.
UK bills often quote both therms and kWh.
In metric-dominant EU, gas is billed in kWh or m³.

Avoid these

Comparing therms and kWh without conversion on a mixed-unit bill.
Assuming therms are used globally — only US and UK.
Using BTU when bill shows therms — factor of 100,000.

Frequently asked questions

How many electronvolts in a therm?
