Convert kiloelectron volt to j
Kiloelectron volt
The kiloelectron volt (keV) is a unit of energy equal to one thousand electron volts, or approximately 1.602 × 10⁻¹⁶ joules. It is used in X-ray physics, medical imaging, and atomic spectroscopy to describe the energies of X-ray photons and low-energy charged particles. Diagnostic X-rays typically have photon energies in the range of tens to hundreds of keV.
Joule
The joule (/dʒaʊ,dʒuːljawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).
