This article will show how to convert voltage measurement units from megavolts (MV) to millivolts (mV). We will cover essential definitions, provide examples, share relevant formulas, and present tables, along with answers to common questions.
Definitions of Volt, Megavolt, and Millivolt
Let’s get started by understanding the key definitions of Volt (V), Megavolt (MV) and Millivolt (mV). Understanding these terms will allow you to perform conversions confidently.
What is Volt (V)?
A volt (V) is the SI (International System of Units) unit of electric potential and voltage. It measures the difference in electric energy between two points in a circuit. One volt means one ampere of current uses one watt of power.[1]
According to SI prefixes[2], which are based on powers of 10, a volt (1 V) is equivalent to one-millionth megavolts, or 10-6 MV, or 0.000001 MV.
What is Megavolt (MV)?
A megavolt (MV) is a unit of electrical potential equal to one million volts (1,000,000 V). Think of it like comparing the height of a building to a mountain. Megavolts help quantify extremely high voltages where standard volt measurements are impractical.
What is Millivolt (mV)?
A millivolt (mV) is a unit of electrical potential equal to one-thousandth (1/1,000) of a volt (0.001 V). It is widely utilized in applications requiring precise measurement of low voltages, such as sensor outputs (e.g., temperature, biomedical devices) and small-scale electronic circuits where minimal electrical signals must be accurately captured and analyzed. Its compact scale makes it ideal for systems sensitive to higher voltage levels.
MV to mV formula
Let’s take a closer look at the conversion formula so you can carry out these conversions independently, whether using a calculator or doing it manually with pencil and paper.
The mega- prefix in the International System of Units (SI) represents a multiplier of 106 (1,000,000) while the milli- represents a multiplier of 10-3 (0.001) .
So, to convert from megavolts to millivolts, multiply the number of megavolts (V(MV)) by 109 or 1,000,000,000.
V(mV) = V(MV) × 109 = V(MV) × 1,000,000,000
Or remember the MV-to-mV conversion factor: 1 MV = 109 = 1,000,000,000 mV

Examples
Now, let's look at an example that illustrates the calculations required to convert from megavolts to millivolts (MV to mV).
Example: Voltage Regulation in High-Capacity Servers
Large-scale data centers operate using high-energy power supplies rated in megavolts, but internal diagnostics require millivolt precision to monitor fluctuations affecting server performance and cooling systems.
If the data center operates at 3.2 megavolts, how many millivolts is that? You need to know this to analyze voltage stability in high-capacity server racks.
Solution
Since 1 megavolt (MV) = 109 = 1,000,000,000 millivolts (mV), we can convert 3.2 MV to millivolts by using the following formula:
Therefore, the data center operates at 3.2 MV is equivalent to 3,200,000,000 mV.
To solve the problem with our calculator, follow the steps below:
- Enter the value in megavolts – For this example, enter
3.2into theFrombox. - View the result – The converter instantly calculates and displays the equivalent value in millivolts:
3,200,000,000 mV.
FAQs
Is 1 megavolt or 1 millivolt larger?
A megavolt (MV) is a billion times bigger than a millivolt (mV). Here are the relationships between the units:
1 MV = 109 = 1,000,000,000 mV1 mV = 10-9 = 1 ÷ 1,000,000,000 = 0.000000001 MV
How to convert from megavolts to millivolts?
To convert voltage from megavolts (MV) to millivolts (mV), follow these simple steps:
