Convert electric potential between volts, millivolts, microvolts, kilovolts, megavolts and CGS units.
| Conversion | Result | Formula |
|---|---|---|
| Millivolts to volts | 1 mV = 0.001 V | volts = millivolts ÷ 1,000 |
| Volts to millivolts | 1 V = 1,000 mV | millivolts = volts × 1,000 |
| Kilovolts to volts | 1 kV = 1,000 V | volts = kilovolts × 1,000 |
| Volts to kilovolts | 1 V = 0.001 kV | kilovolts = volts ÷ 1,000 |
| Unit | Symbol | Equal to |
|---|---|---|
| Volt | V | 1 V |
| Megavolt | MV | 1,000,000 V |
| Kilovolt | kV | 1,000 V |
| Millivolt | mV | 0.001 V |
| Microvolt | µV | 0.000001 V |
| Nanovolt | nV | 0.000000001 V |
| Abvolt | abV | 0.00000001 V |
| Statvolt | statV | 299.79246 V |
Voltage, or electric potential difference, is the “pressure” that pushes charge through a circuit. One volt drives one ampere of current through one ohm of resistance (Ohm’s law: V = I × R).
| Source | Typical voltage |
|---|---|
| Nerve cell signal | about 70 mV |
| AA battery | 1.5 V |
| USB port | 5 V |
| Car battery | 12 V |
| Household mains | 110–240 V |
| Power transmission lines | 110–765 kV |
Metric prefixes scale the volt in steps of 1,000: 1 kV = 1,000 V and 1 V = 1,000 mV.
There are 1,000 millivolts in one volt.
One kilovolt is 1,000 volts.
The statvolt is the CGS electrostatic unit of potential, equal to 299.792458 volts.
