How the formula works
Both kilovolt and milliwatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in kilovolts by 1.000000e+06 to get milliwatts. To reverse the conversion, multiply a milliwatt value by 0.000001 to get back to kilovolts.
Frequently asked questions
What is Kilovolt (kV)?
A Kilovolt (kV) equals 1,000 volt(s), a scaled unit of electric potential used for kilo-scale electrical work.
What is Milliwatt (mW)?
A Milliwatt (mW) equals 1/1,000 watt(s), a scaled unit of electrical power used for milli-scale electrical work.
How do I convert kilovolts to milliwatts?
Multiply the kilovolt value by 1.000000e+06 to get the equivalent in milliwatts. For example, 5 kV × 1.000000e+06 = 5.000000e+06 mW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+06 is an exact, non-rounded value.
Can I convert milliwatts back to kilovolts?
Yes. Divide the milliwatt value by 1.000000e+06, or multiply it by 0.000001, to get kilovolts.
