How to Convert Millivolts to Megavolts
To convert millivolts to megavolts, multiply the voltage by the following conversion ratio: 1e-9 megavolts/millivolt.
Since one millivolt is equal to 1e-9 megavolts, you can use this simple formula to convert:
The voltage in megavolts is equal to the voltage in millivolts multiplied by 1e-9.
For example, here's how to convert 5 millivolts to megavolts using the formula above.
How Many Megavolts Are in a Millivolt?
There are 1e-9 megavolts in a millivolt, which is why we use this value in the formula above.
Our millivolt to megavolt calculator automatically converts your voltage measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Millivolts and megavolts are both units used to measure voltage. Keep reading to learn more about each unit.
What Is a Millivolt?
A millivolt is a unit of voltage equal to 1/1,000 of a volt (0.001 V). One-thousandth of a Volt (0.001 V). [1]
The millivolt is classified as a metric and SI-compatible unit of voltage. Millivolts can be abbreviated as mV; for example, 1 millivolt can be written as 1 mV.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millivolt (mV) a convenient decimal multiple of the volt (V).
In practice, millivolts (mV) are widely used across fine-tolerance laboratory, analytical, and micro-scale voltage measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Megavolt?
A megavolt is a unit of voltage equal to 1,000,000 volts (V), the base unit for voltage. Equal to 1,000,000 Volts. [2]
The megavolt is classified as a metric and SI-compatible unit of voltage. Megavolts can be abbreviated as MV; for example, 1 megavolt can be written as 1 MV.
In the metric system, "mega" is the standard SI prefix for millions, or 10⁶. This makes the megavolt (MV) a convenient decimal multiple of the volt (V).
In practice, megavolts (MV) are widely used across large-scale industrial, bulk, and macro-level voltage specifications within SI metric workflows, engineering documentation, and technical data sheets.
When converting voltage between millivolts (mV) and megavolts (MV), keep full floating-point precision (1 mV = 1e-9 MV; 1 MV = 1,000,000,000 mV) during intermediate calculations and round only the final megavolt figure to match your instrument tolerance.
