What is Voltage Conversion?

Voltage conversion is the process of converting electrical potential difference measurements from one unit to another. Our voltage converter tool makes it easy to switch between different prefixes of the volt, the SI unit of electrical potential.

Common units include volts (V), millivolts (mV), kilovolts (kV), and microvolts (μV). These conversions are essential for electrical engineering, electronics, power systems, and circuit design where different voltage levels are encountered.

Simply enter your value in the "From" field, select the original unit, choose your target unit in the "To" field, and the converter will instantly display the converted result along with the conversion formula.

Voltage Conversion Examples

Electronics Example

Working with sensor and circuit voltages:

  • 5V = 5000 mV = 0.005 kV
  • 3.3V = 3300 mV
  • 1.8V = 1800 mV

Power Systems Example

Converting transmission voltage levels:

  • 110kV = 110,000 V
  • 230V = 0.23 kV
  • 400kV = 400,000 V

Audio and Signal Example

Audio equipment and signal levels:

  • 0.775V = 775 mV (0 dBu)
  • 1V = 1000 mV
  • 0.316V = 316 mV (-8 dBV)

Frequently Asked Questions

How many millivolts in a volt?

One volt equals exactly 1000 millivolts (mV). This is a standard metric prefix conversion where "milli" means one-thousandth.

How do I convert kV to V?

To convert kilovolts to volts, multiply by 1000. For example, 10 kV × 1000 = 10,000 V. The prefix "kilo" means one thousand.

What are common household voltage standards?

Common household voltages: US/Japan = 100-127V, Europe/Asia = 220-240V, Industrial = 380-480V. These are nominal values that can vary slightly.

How many microvolts in a millivolt?

One millivolt (mV) equals 1000 microvolts (μV). For sensitive electronic measurements like thermocouples or biomedical signals, microvolt conversions are common.

What is the formula for V to kV conversion?

To convert volts to kilovolts, divide by 1000. For example, 5000 V ÷ 1000 = 5 kV. This is commonly used when working with high-voltage systems.
