Our physics lectures were all done with CGS units. One of the profe= ssors went through Dimensional Analysis very thoroughly, but when I asked= why capacitance had two different values depending on whether we were in= the magnetic or electrostatic mode he got very shirty. In our standard te= xtbook (written of course by him) he refused even to mention MKS although= it was already coming into use. My roommate was in a worse state. He had of course had a normal English ed= ucation in feet and inches but had done physics in MKS. He could not under= stand why he had to learn these two new systems which both went under the= name of CGS. He got a First anyway. John F5VLF
