Rendered to 6 significant figures.
Formula
Formula
kV = mV × 1e-6
Multiply any value in millivolts by 1e-6 to obtain the value in kilovolts.
Worked example
Convert 1.00000e+6 mV to kV.
- 01Start with 1.00000e+6 mV.
- 02Multiply by the conversion factor: 1.00000e+6 × 1e-6 = 1 kV.
Result1.00000e+6 mV = 1 kV

FAQ
What is the conversion factor from mV to kV?
1 mV equals 1e-6 kV. To convert, multiply the value in millivolts by 1e-6.
How do I convert 1 mV to kV?
1 mV = 1e-6 kV. For any value, multiply by 1e-6.
How do I convert kV back to mV?
Divide by the same factor — or equivalently, multiply by 1000000. So 1 kV = 1.00000e+6 mV.
When would I need to convert millivolt to kilovolt?
Voltage conversions between mV and kV are routine in instrumentation, power-system analysis and electronics design. Volts and kilovolts dominate power-system documents (LV/MV/HV switchgear, motor ratings), while millivolts and microvolts appear on transducer datasheets, thermocouple signal chains and low-level analog measurements.
Is the conversion exact?
Yes. Both mV and kV are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
