Electric potential converter Convert potential difference across volts, SI prefixes, and historical CGS voltage references without losing the base-voltage anchor.
Presets
What this converter covers
The calculator treats electric potential difference, or voltage, as a pure unit conversion. It covers common supply and signal levels plus statvolt and abvolt references for older CGS materials, and it allows signed values when a voltage is measured relative to a chosen reference point.
Result
12,000 mV
12 V equals 12 V. The headline follows your target unit; the grouped sheet keeps the readable V scale visible.

Electric potential converter: voltage, volts, prefixes, statvolts, and abvolts
An electric potential converter, or voltage converter, expresses one potential difference across the SI volt family and the historical CGS units that still appear in older electrical and electrostatics references. It is useful when a source value is written in microvolts, millivolts, kilovolts, statvolts, or abvolts and you want one direct target-unit answer plus a clean sheet that anchors everything back to volts.
What this electric potential converter covers
This page converts an electric potential difference across microvolts, millivolts, volts, kilovolts, megavolts, gigavolts, statvolts, and abvolts. Unlike a bare volt to millivolt converter, it keeps the chosen target unit and the full unit sheet visible at the same time.
That mix covers everyday electronics and power-system scales while still supporting the historical reference units that occasionally appear in CGS-focused material. Signed values are allowed because a measured voltage or electric potential difference can be positive or negative relative to the reference point chosen for the circuit, field, or instrument.
Volts remain the common anchor
The converter first resolves the entered unit into volts. Every other value in the result sheet is simply the same potential difference expressed at another SI scale or in one of the historical CGS voltage systems.
Keeping the volt baseline visible helps when you need to cross-check a modern supply value against an older notation without losing track of the actual magnitude. The direct target selector is there for quick pairwise searches such as volts to millivolts, kilovolts to volts, microvolts to volts, statvolts to volts, or abvolts to volts.
Large SI prefixes keep high-voltage values readable without changing the underlying quantity.
1 mV = 10^-3 V; 1 µV = 10^-6 V
Small-signal work often reads more naturally in millivolts or microvolts.
1 statV ≈ 299.792458 V; 1 abV = 10^-8 V
The historical CGS voltage units are included for older electrostatic and electromagnetic references.
When the historical units matter
Most modern component, power, and measurement work stays entirely in SI units. The historical section matters mainly when you are reading legacy material or comparing older CGS derivations against current SI-based expressions.
The grouped layout keeps those reference units visible without crowding the common SI values that most users care about first.
Why signed voltage values are valid
Electric potential is always measured relative to a reference. In circuit work, a node can be described as negative voltage relative to ground; in field or electrostatics work, the sign tells you the direction of the potential difference you chose to describe. A unit converter should preserve that sign rather than reject it.
The sign does not change the unit factor. For example, -12 V is -12,000 mV and -0.012 kV. The converter therefore treats the sign as part of the value and applies the same volt, millivolt, kilovolt, statvolt, and abvolt factors to the signed quantity.
Worked examples: common voltage conversions
If a small electronics signal is 2500 mV, the converter divides by 1000 to show 2.5 V. If a transmission or test value is 1.2 kV, the converter multiplies by 1000 to show 1200 V. These are scale changes only; they do not describe current, power, or stored energy.
A historical example is 1 statV. The sheet shows it as about 299.792458 V, while 1 abV is 0.00000001 V. Those rows are mostly useful for older CGS references, but keeping them beside SI prefixes helps prevent magnitude mistakes.
2500 mV = 2.5 V; 1.2 kV = 1200 V
Common SI prefix conversions move the decimal point while preserving the same potential difference.
-12 V = -12,000 mV = -0.012 kV
Signed voltage conversions preserve the sign because the sign belongs to the chosen reference direction.
What this converter does not calculate
This calculator does not estimate current, power, resistance, electric field, or stored energy. It converts one voltage quantity into equivalent unit expressions only.
Use it as a reference and planning tool. If the next step depends on a circuit relationship, switch to the calculator that models voltage together with current, resistance, charge, or power directly.
Frequently asked questions
Why show both volts and kilovolts for the same value?
Because the most readable unit depends on scale. A value that looks awkward in volts may be much clearer in kilovolts or megavolts, even though the underlying potential is unchanged.
What are statvolts and abvolts used for?
They are historical CGS-system voltage units. They are uncommon in modern component and power work but still appear in older electrostatics and electromagnetics references.
Does this tell me how much power a voltage source can deliver?
No. Power depends on current as well as voltage. This page only converts the electric-potential quantity itself between units.
Is an electric potential converter the same as a voltage converter?
For unit-conversion purposes, yes. Voltage is electric potential difference, so searches for an electric potential converter, voltage converter, volt converter, or volts to millivolts converter are usually asking for the same unit-scale operation.
Can voltage be negative in this converter?
Yes. A signed voltage is valid when the value is measured relative to a chosen reference point or direction. The converter preserves the sign and applies the same unit factors, so -12 V becomes -12,000 mV and -0.012 kV.
How many millivolts are in one volt?
One volt is 1000 millivolts. The reverse is also useful: one millivolt is 0.001 volts.
How many volts are in one kilovolt?
One kilovolt is 1000 volts. A value such as 1.2 kV is therefore 1200 V.
Why include statvolts and abvolts?
Statvolts and abvolts are historical CGS voltage units. They are uncommon in modern circuit work, but they still appear in older electrostatics and electromagnetics references, so the converter keeps them available beside modern SI units.
