Is energy measured in joules

WebA joule is the SI base unit for energy. It is equal to 1 k g m 2 s 2. [1] In physical terms, lifting an apple one meter takes 1 joule of energy. This should not be confused with a watt which is a unit of power and a rate of how fast energy is used. WebElectronvolt (eV): Energy gained/lost by an electron through an electric potential difference of one volt, e.g., the energy of a visible light photon is measured in eV. British thermal unit (BTU): Energy needed to raise the temperature of one pound of water by one degree Fahrenheit, e.g., burning a cubic foot of natural gas releases ~1,000 BTUs.
