Kerma was the capital city of the Kingdom of Kerma, which was located in present day Egypt and Sudan. Kerma is one of the largest Nubian archaeological sites. It has produced decades of extensive excavations and research, including thousands of graves and tombs and the residential quarters of the main city surrounding the Western/Lower Deffufa. The Kerma site has been confirmed by archaeology to be at least 9,500 years old.


Kerma is an acronym for "kinetic energy released per unit mass", defined as the sum of the initial kinetic energies of all the charged particles liberated by uncharged ionizing radiation in a sample of matter, divided by the mass of the sample. It is defined by the quotient .
