How to Convert Millivolts to Microvolts
To convert millivolts to microvolts, multiply the voltage by the following conversion ratio: 1,000 microvolts/millivolt.
Since one millivolt is equal to 1,000 microvolts, you can use this simple formula to convert:
The voltage in microvolts is equal to the voltage in millivolts multiplied by 1,000.
For example, here's how to convert 5 millivolts to microvolts using the formula above.
How Many Microvolts Are in a Millivolt?
There are 1,000 microvolts in a millivolt, which is why we use this value in the formula above.
Our millivolt to microvolt calculator automatically converts your voltage measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Millivolts and microvolts 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 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). [2]
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.
When converting voltage between millivolts (mV) and microvolts (µV), keep full floating-point precision (1 mV = 1,000 µV; 1 µV = 0.001 mV) during intermediate calculations and round only the final microvolt figure to match your instrument tolerance.
