  2. Electronvolt - Wikipedia

    en.wikipedia.org/wiki/Electronvolt

    In general, the masses of all hadrons are of the order of 1 GeV/c 2, which makes the GeV/c 2 a convenient unit of mass for particle physics: [4] 1 GeV/ c 2 = 1.782 661 92 × 10 −27 kg . The atomic mass constant ( m u ), one twelfth of the mass a carbon-12 atom, is close to the mass of a proton.

  4. Units of energy - Wikipedia

    en.wikipedia.org/wiki/Units_of_energy

    A unit of electrical energy, particularly for utility bills, is the kilowatt-hour (kWh); [3] one kilowatt-hour is equivalent to 3.6 megajoules. Electricity usage is often given in units of kilowatt-hours per year or other periods. [4] This is a measurement of average power consumption, meaning the average rate at which energy is transferred ...

  5. Photon energy - Wikipedia

    en.wikipedia.org/wiki/Photon_energy

    An FM radio station transmitting at 100 MHz emits photons with an energy of about 4.1357 × 10 −7 eV. This minuscule amount of energy is approximately 8 × 10 −13 times the electron's mass (via mass–energy equivalence). Very-high-energy gamma rays have photon energies of 100 GeV to over 1 PeV (10 11 to 10 15 electronvolts) or 16 nJ to 160 ...

    The definition of the joule as J = kg⋅m 2 ⋅s −2 has remained unchanged since 1946, but the joule as a derived unit has inherited changes in the definitions of the second (in 1960 and 1967), the metre (in 1983) and the kilogram . [14]
