Examples
| 1 V | 0.001 kV |
| 5 V | 0.005 kV |
| 10 V | 0.01 kV |
| 100 V | 0.1 kV |
One volt equals 0.001 kilovolts (kV). To convert volts to kilovolts, multiply by 0.001; to go back the other way, multiply by 1000 instead.
The converter above does it as you type and shows the working underneath, so you can check the arithmetic rather than take the number on trust.
What volts and kilovolts actually measure
Volt (V) — The volt is the SI unit of potential difference — one joule per coulomb. Batteries, mains supply and virtually all electronics.
Kilovolt (kV) — A kilovolt is a thousand volts. Distribution networks, X-ray tubes and ignition systems.

How to convert volts to kilovolts by hand
Multiply the number of volts by 0.001.
For example, 25 V × 0.001 = 0.025 kV.
Going the other way, divide by 0.001 — or multiply by 1000, which is the same thing and easier to do in your head.
Everything runs in your browser
There is no server involved in the calculation. The numbers you type never leave your device, nothing is logged, and the page keeps working with no connection once it has loaded. That is not a marketing line — it is simply how the tool is built, because a calculation like this has no reason to touch a network.
Questions people ask
How many kV are in 1 V?
1 V equals exactly 0.001 kV. Multiply any value in volt by 0.001 to get kilovolt.
Is anything uploaded to a server?
No. The whole calculation happens in your browser. Nothing is sent anywhere, and the page keeps working offline once loaded.
