Voltage Converter – Convert Volts, mV, kV and MV

How to Use the Voltage Converter

Enter a voltage value, select the source unit and choose the target unit to convert between volts, millivolts, kilovolts and megavolts.

Practical Example

5 kV equals 5,000 V and 5,000,000 mV.

Factors That Affect Voltage Measurements

Meter accuracy, probe placement, circuit loading, waveform shape and electrical noise can influence measured voltage. The converter changes units only.

Frequently Asked Questions

How many millivolts are in one volt?

1,000 mV.

How many volts are in one kilovolt?

1,000 V.

Does this calculate electrical power?

No. Power also depends on current and circuit conditions.

Understanding Voltage Units

Voltage is electric potential difference and is measured in volts, with millivolts, kilovolts and megavolts used for smaller or larger values. Metric prefixes differ by powers of one thousand.

Converting the unit does not change the electrical condition. Current, resistance, insulation rating and circuit topology remain separate considerations, so use the converted voltage together with the appropriate system specifications.

Unit Relationship and Practical Context

Voltage units differ by metric prefixes, so 1 kV = 1,000 V and 1 mV = 0.001 V. Converted magnitude does not indicate whether a value is AC RMS, AC peak or DC; preserve that electrical context.
