About these units
Electronvolt (eV)
- Definition
- An electronvolt (eV) is the energy gained by an electron moving through a one-volt potential, a tiny amount of energy.
- History
- It became standard in atomic and particle physics in the 20th century.
- Current use
- Electronvolts measure energies of particles, photons, and chemical bonds.
British Thermal Unit (BTU)
- Definition
- A British thermal unit (BTU) is the energy needed to raise one pound of water by one degree Fahrenheit.
- History
- It developed with steam engineering in Britain and the United States.
- Current use
- BTUs rate heating, air-conditioning, and appliance energy in the US.
