Voltage Converter
What this does
Converts electric potential between volts, millivolts, kilovolts and microvolts.
Handy anchors
- Household mains: 110–120 V (Americas, Japan at 100 V) or 220–240 V (most of the world). USB: 5 V. Car battery: 12 V.
Good to know
Converting the number does not convert the electricity — a 110 V appliance still needs a transformer on a 220 V supply.
