'NAMESAKE' Scientists who have SI Units named after them
Many scientists have been recognized with the assignment of their names as international units by the International Committee for Weights and measures or as non-SI units. The International System of Units (abbreviated SI : Système international d'unités) is the most widely used system of units of measurements.
