How to convert kilovolts to millivolts
mV = kV × 1,000,000Multiply the value in kilovolts by 1,000,000. To go the other way, multiply by 0.000001 (or divide by 1,000,000).
A kilovolt is larger than a millivolt: one kilovolt contains 1,000,000 millivolts.

About the units
Kilovolt (kV)
The kilovolt (kV) is a unit of electric potential (voltage) in the International System of Units (SI). One kilovolt equals 1,000 volts (V).
Millivolt (mV)
The millivolt (mV) is a unit of electric potential (voltage) in the International System of Units (SI). One millivolt equals 0.001 volts (V).
Frequently asked questions
How many millivolts are in one kilovolt?
There are 1,000,000 millivolts in one kilovolt, and this value is exact by definition.
How do I convert kilovolts to millivolts?
Multiply the number of kilovolts by 1,000,000. For example, 10 kV × 1,000,000 = 10,000,000 mV.
How many kilovolts are in one millivolt?
One millivolt equals 0.000001 kilovolts. That is the reverse factor, 1 ÷ 1,000,000.
What is 10 kilovolts in millivolts?
10 kV = 10,000,000 mV.
Is this kV to mV converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
