How to Convert Millivolts to Kilovolts
To convert millivolts to kilovolts, multiply the voltage by the following conversion ratio: 0.000001 kilovolts/millivolt.
Since one millivolt is equal to 0.000001 kilovolts, you can use this simple formula to convert:
The voltage in kilovolts is equal to the voltage in millivolts multiplied by 0.000001.
For example, here's how to convert 5 millivolts to kilovolts using the formula above.
How Many Kilovolts Are in a Millivolt?
There are 0.000001 kilovolts in a millivolt, which is why we use this value in the formula above.
Our millivolt to kilovolt calculator automatically converts your voltage measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Millivolts and kilovolts 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 Kilovolt?
A kilovolt is a unit of voltage equal to 1,000 volts (V), the base unit for voltage. High-voltage power distribution unit (1,000 V). [2]
The kilovolt is classified as a metric and SI-compatible unit of voltage. Kilovolts can be abbreviated as kV; for example, 1 kilovolt can be written as 1 kV.
In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilovolt (kV) a convenient decimal multiple of the volt (V).
In practice, kilovolts (kV) 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 kilovolts (kV), keep full floating-point precision (1 mV = 0.000001 kV; 1 kV = 1,000,000 mV) during intermediate calculations and round only the final kilovolt figure to match your instrument tolerance.
