Common voltage conversion mistakes

  • The volt measures potential and the watt measures power. A 12 V battery says nothing about power until the current is known: 12 V at 2 A is 24 W, 12 V at 10 A is 120 W.
  • The µ prefix is often written u in datasheets and on components, because the character is missing from ordinary keyboards. uV and µV are the same unit, the microvolt, one millionth of a volt.
  • The millivolt and the megavolt are a factor of a billion apart and are written mV and MV. Upper and lower case carry the whole difference, exactly as between mW and MW in power.
