This article will show how to convert voltage measurement units from microvolts (µV) to megavolts (MV). We will cover essential definitions, provide examples, share relevant formulas, and present tables, along with answers to common questions.
Definitions of Volt, Microvolt, and Megavolt
Let’s get started by understanding the key definitions of Microvolt (µV)
, Megavolt (MV)
, and Volt (V)
. 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 million microvolts, or 106 µV
, or 1,000,000 µV
.

What is Microvolt (µV)?
A microvolt (µV) is a unit of electrical potential equal to one-millionth (1/1,000,000
) of a volt (0.000001 V
). It is commonly used in applications requiring high-precision voltage measurements, such as biomedical sensors (e.g., EEG and ECG devices), seismic monitoring, and radio signal detection, where extremely small electrical signals must be accurately captured and analyzed.

Its fine resolution makes it essential for systems sensitive to even the slightest voltage variations.
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.

µV 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 micro-
prefix in the International System of Units (SI) represents a multiplier of 10-6 (0.000001)
while the mega-
represents a multiplier of 106 (1,000,000)
.
So, to convert from microvolts to megavolts, divide the number of microvolts (V(µV)
) by 1012 (1,000,000,000,000)
.
V(MV) = V(µV) ÷ 1012 = V(µV) ÷ 1,000,000,000,000
Or remember the µV-to-MV
conversion factor: 1 µV = 10-12 = 0.000000000001 MV

Examples
Now, let's look at an example that illustrates the calculations required to convert from microvolts to megavolts (µV to MV).
Example: Nuclear Reactor Insulation Testing
Reliable insulation is crucial for safety in nuclear reactors. Reactor components undergo high-voltage testing to ensure insulating materials can handle operational extremes, preventing catastrophic failures.
Suppose a high-voltage insulation test produces a sensor reading of 2,250,000,000,000 µV
. To facilitate analysis and comparison, you need to convert the reading to megavolts (MV).
Solution
Since 1 megavolt (MV) = 1012 = 1,000,000,000,000 microvolts (µV)
, we can convert 2,250,000,000,000 µV
to megavolts by using the following formula:
Therefore, the 2,250,000,000,000 µV
output voltage of the sensor is equivalent to 2.25 MV
.
To solve the problem with our calculator, follow the steps below:

FAQs
Is 1 megavolt or 1 microvolt larger?
A megavolt (MV) is a trillion times bigger than a microvolt (µV). Here are the relationships between the units:
1 MV = 1012 = 1,000,000,000,000 µV
1 µV = 10-12 = 1 ÷ 1,000,000,000,000 = 0.000000000001 MV
