Examples

1 MV1000000 V
5 MV5000000 V
10 MV10000000 V
100 MV100000000 V

One megavolt equals 1000000 volts (V). To convert megavolts to volts, multiply by 1000000; to go back the other way, multiply by 1.0000e-6 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 megavolts and volts actually measure

Megavolt (MV) — A megavolt is a million volts. High-voltage transmission and particle accelerators.

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