Template:Short description Template:Refimprove This is a list of scientific units named after people. For other lists of eponyms (names derived from people) see eponym. By convention, the name of the unit is properly written starting with a lowercase letter (except where any word would be capitalized), but the first letter of its symbol is a capital letter if it is derived from a proper name.
