Siemens is the SI unit for (trans)conductance. Like all units named after people: - its symbol (S) is capitalized; - its name (siemens) is not (unless starting a sentence). Note that since it's named after a person named Ernsr Werner von Siemens, it's called "siemens" even in singular (1 S = 1 siemens). According to normal English nomenclature then the plural would be siemenses, but that doesn't seem to have caught on. ms means milliseconds. Seconds is the SI unit for time. Like all units not named after people: - neither its symbol (s) nor its name (second) is capitalized. -hpa
