This page converts megavolts into volts using the factor 1,000,000, and shows the reverse figure alongside it. Both units measure the electrical potential difference driving a current, which is why one number does the whole job.
One mega volt is a million of a volt (1e6 volts). The volt is the SI unit of electric potential: one joule of energy per coulomb of charge moved.
The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in volts, so you can sanity-check whether your answer is a plausible size.
The formula
megavolts- The amount you are converting, in megavolts
1,000,000- The exact number of volts in one megavolt
volts- The converted result
How it works, step by step
- Enter the value in megavolts.
- It is multiplied by 1,000,000, 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
UK mains: 0.00023 MV in volts
At 0.00023 MV (uk mains), the same quantity in volts is 0.00023 × 1e+06 = 230 V. One megavolt is 1e+06 volts, so the numbers grow as expected.
Overhead distribution line: 0.011 MV in volts
Overhead distribution line comes to about 0.011 MV. Multiplying by the factor: 0.011 × 1e+06 = 11,000 V. Dividing the answer back by 1e+06 returns the figure you started with, which is the quickest way to check you have the factor the right way up.

Frequently asked questions
How many volts are in one megavolt?
Exactly 1,000,000. 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 megavolts to volts?
volts = megavolts × 1,000,000. Reversed, megavolts = volts ÷ 1,000,000, which is the same as multiplying by 1e-06.
Which is the bigger unit, the megavolt or the volt?
The megavolt. One megavolt equals 1e+06 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 megavolt?
One mega volt is a million of a volt (1e6 volts).
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.
