Metrication in the United States There are no U.S. customary units for electric current, potential difference, or charge since these concepts were developed after the international adoption of metric in science. The metric units ampere, volt, ohm and coulomb are the only units used. The SI term hertz has replaced the term "cycles per second" as a unit of frequency. Energy is often measured in watt hours, BTUs, therms or calories rather than the SI joule. Residential and commercial electrical energy use is metered and billed in kilowatt hours, kW·h, as in most metric countries. Force measurements regularly use the pound instead of the SI
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.
