What is a Voltage?
The Electric Potential Converter converts voltage between volts and its common sub-units — millivolts, microvolts, kilovolts, and megavolts — plus the CGS units abvolt and statvolt. Voltage spans a huge practical range: sensor outputs are measured in millivolts or microvolts, household electricity in volts, and power transmission lines in kilovolts, so converting accurately between these scales matters across electronics, power systems, and lab work.
Enter a value in any supported unit and the converter calculates the equivalent instantly. For related electrical quantities, see the Electric Current Converter for amperage and the Electric Resistance Converter for resistance.
How to use this Voltage calculator
- Choose your starting unit from the source dropdown — for example, "Millivolts (mV)".
- Enter the numeric value you want to convert in the input field.
- Choose your target unit from the destination dropdown — for example, "Volts (V)".
- Read the converted result, which updates instantly as you type or change units.
- Use the swap (⇅) button if you need to reverse the conversion direction.
- Use the copy button to grab the result for a datasheet comparison, lab report, or circuit calculation.
Formula & Methodology
The converter's base unit is the volt (V). Every supported unit has a fixed multiplier to volts: - 1 megavolt (MV) = 1,000,000 V - 1 kilovolt (kV) = 1,000 V - 1 millivolt (mV) = 0.001 V - 1 microvolt (µV) = 0.000001 V - 1 abvolt (CGS) = 0.00000001 V - 1 statvolt (CGS) ≈ 299.79 V Any conversion follows: Result = Input × (toBase of source unit ÷ toBase of target unit) Worked example — converting 3.3 V (a common logic-level voltage) to millivolts: Result = 3.3 × (1 ÷ 0.001) = 3,300 mV This confirms a common reference point in digital electronics, where 3.3V logic levels are frequently compared against sensor outputs specified in millivolts.
Frequently Asked Questions
Divide the millivolt value by 1,000, since one volt equals 1,000 millivolts. Enter your value with 'Millivolts (mV)' as the source unit and 'Volts (V)' as the target and the converter applies this automatically.
A volt (V) is the SI unit of electric potential, while a millivolt (mV) is one-thousandth of a volt — sensor outputs, thermocouples, and biological signals like ECG readings are often measured in millivolts because the actual voltages involved are very small.
Household outlets deliver voltage in the 110-240V range depending on the country, a scale that's practical to express in whole volts, while long-distance power transmission lines operate at tens or hundreds of thousands of volts to reduce transmission losses — kilovolts keep those larger numbers manageable.
Microvolts (µV) measure extremely small voltage signals — certain biomedical signals like EEG readings, or noise floor specifications in sensitive audio and RF electronics, where even a millivolt would be too coarse a unit.
Multiply the kilovolt value by 1,000, since one kilovolt equals 1,000 volts. This conversion comes up often when comparing power transmission or high-voltage equipment specifications against standard low-voltage electronics.
Abvolt and statvolt are CGS (centimetre-gram-second) electromagnetic units of electric potential, included for physics and engineering contexts that still reference CGS units in older textbooks or specialised research. See the [CGS to SI Units Converter](/cgs-si-converter/) for more CGS-to-SI conversions.
Voltage, current, and resistance are related by Ohm's Law (V = I × R) — if you know two of the three values, you can calculate the third. Use the [Ohm's Law Calculator](/ohms-law-calculator/) alongside this converter for a complete circuit calculation.
Yes — if the [Voltage Drop Calculator](/voltage-drop-calculator/) gives you a result in volts and you need it in millivolts (or vice versa) for a spec comparison, this converter handles that unit conversion directly.
Voltage and EMF are both measured in volts and are closely related, but EMF specifically refers to the energy supplied per unit charge by a source (like a battery) before any internal resistance losses, while voltage more generally refers to the potential difference measured anywhere in a circuit.
For microvolt and millivolt-scale sensor signals, keep several significant figures in your conversion, since these small values are often compared against similarly small threshold or noise-floor specifications where rounding can matter.
