To convert kilovolts to volts, multiply by 1000. That factor is the whole relationship: both units measure the electrical potential difference driving a current, so the conversion is a proportion with no offset and no substance-specific constant.
The volt is the SI unit of electric potential: one joule of energy per coulomb of charge moved. Kilovolts describe distribution lines, ignition systems and insulation ratings — the level at which air itself starts to conduct.
Below the calculator there is a step table for the values people look up most, and a second table putting real the electrical potential difference driving a current figures into volts so the number you get has something to be compared against.
The formula
kilovolts- The amount you are converting, in kilovolts
1000- The exact number of volts in one kilovolt
volts- The converted result
How it works, step by step
- Enter the value in kilovolts.
- It is multiplied by 1000, the exact factor between the two units.
- The answer is shown in volts, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
USB bus: 0.005 kV in volts
USB bus comes to about 0.005 kV. Multiplying by the factor: 0.005 × 1000 = 5 V. Dividing the answer back by 1000 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
AA alkaline cell: 0.0015 kV in volts
Take aa alkaline cell, roughly 0.0015 kV. The conversion is a single multiplication — 0.0015 × 1000 — giving 1.5 V. Because the relationship is proportional, doubling the input doubles the answer to 3 V.

Frequently asked questions
How many volts are in one kilovolt?
Exactly 1000. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert kilovolts to volts?
volts = kilovolts × 1000. Reversed, kilovolts = volts ÷ 1000, which is the same as multiplying by 0.001.
Which is the bigger unit, the kilovolt or the volt?
The kilovolt. One kilovolt equals 1000 volts.
What does this quantity actually measure?
Both units measure the electrical potential difference driving a current. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a kilovolt?
Kilovolts describe distribution lines, ignition systems and insulation ratings — the level at which air itself starts to conduct.
What is a volt?
The volt is the SI unit of electric potential: one joule of energy per coulomb of charge moved.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
