SI base unit referenced to the values of the fundamental constants, namely the Planck constant ("h"), the electron charge ("e"), the Boltzmann constant ("k"), and the Avogadro constant ("N"). This approach was approved in 2018, only after measurements of these constants were achieved with sufficient accuracy. SI base unit The International System of Units (SI) defines seven units of measure as a basic set from which all other SI units can be derived. The SI base units and their physical quantities are the meter for measurement of length, the kilogram for mass, the second for time, the ampere for electric current, the kelvin
University of Campinas School of Electrical and Computer Engineering University of Campinas School of Electrical and Computer Engineering The School of Electrical and Computer Engineering (, FEEC) is one of the most well-renowned engineering schools in Brazil. It was created in 1967 on UNICAMP's main campus in Campinas, São Paulo, Brazil, as the Department of Electrical Engineering () of the School of Engineering (). It became an independent unit in 1986, renamed the School of Electrical Engineering (). Subsequently, in 1996, it was changed to its current name, adding computer engineering courses in partnership with the Institute of Computing.
