About Converting US therms to Electronvolts
US therm and Electronvolt both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: US therm used for natural gas energy, and an electronvolt is the energy gained by an electron across one volt.
Formula
electronvolts = us therms × 6.583569e+26
This factor comes from each unit's defined relationship to the category's base unit: 1 us therm equals 105480400 base units, and 1 electronvolt equals 1.602177e-19 base units, so dividing one by the other gives the direct us therm-to-electronvolt factor of 6.583569e+26.
Simple example
1 therm × 6.583569e+26 = 6.583569e+26 eV
1 us therm = 6.583569e+26 electronvolts.
Real-world example
100 therm × 6.583569e+26 = 6.583569e+28 eV
100 us therms = 6.583569e+28 electronvolts.

Understanding the US therm (therm)
US therm used for natural gas energy.
Understanding the Electronvolt
Electronvolt (eV) measures energy. The energy gained by a single electron accelerated through an electric potential difference of one volt — a very small amount of energy, exactly 1.602176634 × 10⁻¹⁹ joules. It is classified as a non-SI unit accepted for use with the SI, common in physics.
Where it's used: Standard unit throughout particle physics, atomic physics, and chemistry worldwide
Uses of the Electronvolt today
- Particle physics (particle accelerator energies are often quoted in GeV or TeV)
- Atomic and molecular energy levels
- Semiconductor band-gap energies
Electronvolt — sources
- BIPM SI Brochure, 9th edition — Electronvolt listed as a non-SI unit accepted for use with the SI, with its exact value fixed via the elementary charge.

Frequently asked questions
How many electronvolts are in 1 us therm?
1 us therm equals 6.583569e+26 electronvolts, using the exact defined conversion factor rather than an estimate.
How do I convert us therm to electronvolt?
Multiply the us therm value by 6.583569e+26. The converter above does this instantly to whatever precision you set.
How do I convert electronvolt back to us therm?
Use the reverse factor: 1 electronvolt equals 1.518933e-27 us therms. You can also use the swap control in the converter above to flip the direction instantly.
What is a us therm?
US therm (therm) is a unit of engineering.
What is a electronvolt?
Electronvolt (eV) measures energy. The energy gained by a single electron accelerated through an electric potential difference of one volt — a very small amount of energy, exactly 1.602176634 × 10⁻¹⁹ joules. It is classified as a non-SI unit accepted for use with the SI, common in physics.
Is the us therm to electronvolt conversion exact?
Yes. The energy gained by a single electron accelerated through an electric potential difference of one volt — a very small amount of energy, exactly 1.602176634 × 10⁻¹⁹ joules. That fixed definition is what the converter above uses, so any rounding you see is a display choice, not a limitation of the math.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
