How to Convert Megavolts to Millivolts
To convert megavolts to millivolts, multiply the voltage by the following conversion ratio: 1,000,000,000 millivolts/megavolt.
Since one megavolt is equal to 1,000,000,000 millivolts, you can use this simple formula to convert:
The voltage in millivolts is equal to the voltage in megavolts multiplied by 1,000,000,000.
For example, here's how to convert 5 megavolts to millivolts using the formula above.
How Many Millivolts Are in a Megavolt?
There are 1,000,000,000 millivolts in a megavolt, which is why we use this value in the formula above.
Our megavolt to millivolt calculator automatically converts your voltage measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Megavolts and millivolts are both units used to measure voltage. Keep reading to learn more about each unit.
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. [1]
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.
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). [2]
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.
When converting voltage between megavolts (MV) and millivolts (mV), keep full floating-point precision (1 MV = 1,000,000,000 mV; 1 mV = 1e-9 MV) during intermediate calculations and round only the final millivolt figure to match your instrument tolerance.
