How to Convert Microvolts to Millivolts
To convert microvolts to millivolts, multiply the voltage by the following conversion ratio: 0.001 millivolts/microvolt.
Since one microvolt is equal to 0.001 millivolts, you can use this simple formula to convert:
The voltage in millivolts is equal to the voltage in microvolts multiplied by 0.001.
For example, here's how to convert 5 microvolts to millivolts using the formula above.
How Many Millivolts Are in a Microvolt?
There are 0.001 millivolts in a microvolt, which is why we use this value in the formula above.
Our microvolt to millivolt calculator automatically converts your voltage measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Microvolts and millivolts are both units used to measure voltage. Keep reading to learn more about each unit.
What Is a Microvolt?
A microvolt is a unit of voltage equal to 1/1,000,000 of a volt (0.000001 V). One-millionth of a Volt (10⁻⁶ V). [1]
The microvolt is classified as a metric and SI-compatible unit of voltage. Microvolts can be abbreviated as µV; for example, 1 microvolt can be written as 1 µV.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the microvolt (µV) a convenient decimal multiple of the volt (V).
In practice, microvolts (µV) 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 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 microvolts (µV) and millivolts (mV), keep full floating-point precision (1 µV = 0.001 mV; 1 mV = 1,000 µV) during intermediate calculations and round only the final millivolt figure to match your instrument tolerance.
