About this converter

Convert between 6 different units of electric potential. Enter a value and select units to see the conversion result instantly with step-by-step solution.

An Electric Potential Converter helps you change electric potential values from one unit to another in seconds. Electric potential is often shown in volts, but you may also see millivolts (mV), microvolts (µV), kilovolts (kV), or megavolts (MV).

How to Use

  1. Enter Value: Enter the electric potential value you have.
  2. Choose Starting Unit: Select the input unit (e.g., V, mV, kV).
  3. Select Target Unit: Choose the output unit you need.
  4. Get Result: Read the converted result instantly.

What This Calculator Measures

Electric potential (voltage) is the "electrical pressure" that can push electric charge through a circuit. It measures the energy available per unit charge.

Formula or Logic

Unit conversion is done by scaling with powers of 10:

  • 1 kilovolt (kV) = 1,000 volts (V)
  • 1 volt (V) = 1,000 millivolts (mV)
  • 1 millivolt (mV) = 1,000 microvolts (µV)

Example Calculations

  • Example 1: Convert 2.5 V to millivolts.
  • Calculation: 2.5 * 1000 = 2500 mV.
  • Example 2: Convert 780 mV to volts.
  • Calculation: 780 / 1000 = 0.78 V.

Understanding Your Results

Your result represents the same electric potential. Larger units like kV are common in power transmission, while mV and µV are used for sensors and audio signals.

Common Mistakes to Avoid

  • Milli vs Mega: Mixing up mV (millivolt) with MV (megavolt).
  • Unit Scale: Forgetting that kV means thousands of volts, not hundreds.
  • Quantity Type: Confusing voltage with current (amps) or power (watts).

Frequently Asked Questions

Electric potential is the electrical energy available per unit charge. In everyday terms, it is like the "push" that can move charge.
In most practical use, yes. "Voltage" usually means electric potential difference between two points.
Common units include volts (V), millivolts (mV), microvolts (µV), kilovolts (kV), and megavolts (MV). The exact list depends on the tool's unit menu.
Multiply by 1,000. For example, 3 V becomes 3000 mV.
Divide by 1,000. For example, 500 mV becomes 0.5 V.
Voltage is measured relative to a reference point. If the point you measure is below the reference (like ground), the reading can be negative.
No. It only changes how the same value is written. The circuit voltage stays the same.
Use kV when the voltage is large and writing it in volts would be inconvenient (for example, thousands of volts).
Electric potential is a value (like height). The electric field relates to how quickly potential changes over distance (like slope). They describe different things.
Yes. It is helpful for checking unit conversions in electrostatics, circuits, and lab work.
