The 1987 revision of the SUNAMCO ‘Red Book’ has for nearly a quarter of a century provided physicists with authoritative guidance on the use of symbols, units and nomenclature. As such, it is cited as a primary reference by the IUPAC ‘Green Book’ (Quantities, Units and Symbols in
Symbols representing physical quantities, units, mathematical operations and relationships, astronomical bodies, constellations, and the Greek alphabet.
7. The names of units are not capitalized, even if the symbol for it is: newton (N). If we capitalize it (“Newton”), then we are talking about the man, not the unit. 8. The only SI units that have a symbol consisting of more than one letter are pascals (Pa) and webers (Wb). Note the capitalization. 9.
