Voltage Converter
- 11 x 1000 11000 volt
This page converts a voltage from one unit into another. Every value passes through the volt, the SI unit voltage is held in, and voltage stays voltage: a unit only converts inside its own dimension.
How do you convert a voltage between volts, millivolts and kilovolts?
Pick the unit you have, pick the unit you want, and type the value. The page multiplies by the factor between the two and prints the arithmetic under the result, so the answer and the working are the same object.
- Choose the unit your value is in. This page opens on the kilovolt.
- Choose the unit you want it in. This page opens on the volt.
- Type the value. The result and the factor behind it appear together.
- Read the working. It converts into the volt first and out again, which is the same two lines you would write by hand.
Voltage Conversion Table
One row per unit this page offers, each measured against the volt. The last column says whether the factor is a definition or a reading of one.
| Unit | Symbol | In the SI unit | Exact? |
|---|---|---|---|
| microvolt | uV | 0.000001 | exact |
| millivolt | mV | 0.001 | exact |
| volt | V | 1 | exact |
| kilovolt | kV | 1000 | exact |
| megavolt | MV | 1000000 | exact |

What is 11 kV in volts?
- 11 x 1000 11000 volt
11 kV = 11000 V
Where These Factors Come From
Every number above is read from the knowledge base rather than computed for the page. These are the statements it holds for voltage.
- One volt is one watt per ampere, which is one joule per coulomb. This page scales a voltage value between volts and their prefixes; a device that changes mains supply between 120 V and 230 V is a transformer, not a unit conversion.
- An SI prefix multiplies a unit by a power of ten: k is 10^3, M is 10^6, G is 10^9, m is 10^-3, micro is 10^-6 and n is 10^-9. The prefix belongs to the unit, so 1 kV is 1000 V.
- How this page reports a result result in the target volt prefix, plain decimal

| micro | u | 10^-6 |
Is This the Same as a Mains Voltage Converter?
This page rewrites a voltage value between the volt and its prefixes. A device that changes a mains supply from one voltage to another is a transformer, which is hardware rather than a unit conversion, and nothing on this page will size one.
The rule behind this factor is the same for every unit - how SI prefixes scale a unit.
Frequently Asked Questions
What is a voltage converter used for?
On this page it converts a voltage value between volts and their prefixes. A device that changes a mains supply between 120 V and 230 V is a transformer, not a unit conversion.
Can you convert volts to watts?
Not on its own. Power is voltage times current, so a second value is needed; that is a calculation rather than a unit conversion.
How many millivolts are in a volt?
1000 mV.
How many volts is 1 kilovolt?
1000 V.
