How Electric Current Units Are Converted
Electric current units — microamperes, milliamperes, amperes, and kiloamperes — are all powers of ten apart, so converting between them is a single multiplication or division by the right factor of 1,000.
Read guideHow Voltage Units Are Converted
Voltage scales through the same metric-prefix ladder as current — microvolts, millivolts, volts, and kilovolts — each a factor of 1,000 from its neighbor, covering everything from a sensor signal to household mains supply.
Read guideWhy Converting Units First Makes Ohm's Law Work
Ohm's law only gives a correct resistance when current and voltage are both in their standard units first — converting a real 500 mA and 12 V into amps and volts before dividing gives a genuinely correct 24 ohms.
