The standard reference was "H.S. Hvistendahl, Engineering Units and Physical Quantities,Macmillan, 1964. Anyone have something more up to date There were only 6 fundamental Units in MKS are Length L Mass M Time T Thermodynamic Temperature Big-Theta Electric Current I Luminous Intensity ? He also uses Free Energy LF What is nr 7 I forgot. Also Angle [L]-superscript-o so it really is related to length. > (2) Dimensional analysis could extend (from the basic MLT) to temperature, > amount of matter, and electrical current.
