volts to kilovolts | Exact Decimal + Formula
1 Volt = 0.001 Kilovolt
One kilovolt equals exactly a thousand volts. Real-world use: batteries (1.5 v, 9 v), usb (5 v), and household mains (110/230 v). This page expresses those values in kilovolts, which is used for power transmission lines, x-ray tubes, and electric-vehicle powertrains. Enter any value above — the result updates instantly, and a 1–1000 reference table follows below.
About Volt and Kilovolt
Volt (V)
The volt is the SI unit of electrical potential difference.
Where it's used: Batteries (1.5 V, 9 V), USB (5 V), and household mains (110/230 V).
Kilovolt (kV)
A kilovolt is 1,000 volts.
Where it's used: Power transmission lines, X-ray tubes, and electric-vehicle powertrains.

How to Convert Volt to Kilovolt
How many kilovolts are in one volt?
One Volt (V) equals 0.001 Kilovolt (kV). To convert volts to kilovolts, multiply the volt value by 0.001.
How do I convert Volt to Kilovolt?
Multiply your volt value by 0.001 to get the result in Kilovolt: kV = V × 0.001. For example, 5 V = 0.005 kV.
What is the formula for converting V to kV?
The conversion formula is kV = V × 0.001. Use the calculator above for any value, and see the reference table below for common inputs from 0.001 to 1000.
Is there a quick mental estimate for V to kV?
Divide the value by roughly 1000 to quickly estimate the converted result.
