Examples

1 V	1e-9 GV
5 V	5e-9 GV
10 V	1e-8 GV
100 V	1e-7 GV

One volt equals 1.0000e-9 gigavolts (GV). To convert volts to gigavolts, multiply by 1.0000e-9; to go back the other way, multiply by 1.0000e+9 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 gigavolts actually measure

Volt (V) — The volt is the SI unit of potential difference — one joule per coulomb. Batteries, mains supply and virtually all electronics.

Gigavolt (GV) — A gigavolt is a billion volts. Rare outside atmospheric physics and theoretical work.

How to convert volts to gigavolts by hand

Multiply the number of volts by 1.0000e-9.

For example, 25 V × 1.0000e-9 = 2.5000e-8 GV.

Going the other way, divide by 1.0000e-9 — or multiply by 1.0000e+9, which is the same thing and easier to do in your head.

Everything runs in your browser
