Voltage Converters
Convert between electrical potential units used in circuit design, battery systems, power distribution, and voltage rating workflows. This hub applies exact SI volt scaling so conversions from microvolts through megavolts remain consistent and reversible.
Explanation
Electric potential difference describes the energy change per unit charge between two points in an electrical system. The volt (V) is the SI derived unit of electric potential and is defined as one joule per coulomb (1 V = 1 J/C). In SI base terms, voltage is derived from fixed definitions of mass, length, time, and current. Prefix relationships are exact: 1 mV = 10⁻³ V, 1 µV = 10⁻⁶ V, 1 kV = 10³ V, and 1 MV = 10⁶ V. Because these are fixed powers of ten, voltage conversions are purely multiplicative with no offsets. Every factor is computed by reducing both units to volts and simplifying the ratio. This keeps mirror pages mathematically stable and exactly reversible. For clarity, voltage conversions are grouped into base-to-prefix, electronics-scale, and power-scale relationships.
Voltage converters are grouped into directional families so each leaf keeps one stable conversion model.

Frequently Asked Questions
What is voltage?
Voltage is electric potential difference, meaning the energy change per unit charge between two points.
What is a volt?
A volt (V) is the SI derived unit of electric potential difference.
How is voltage related to energy?
Voltage is energy per charge, defined by 1 V = 1 J/C.
What does 1 volt represent?
One volt means each coulomb of charge has one joule of potential energy difference.
Why are millivolts common in electronics?
Sensors, signal chains, and low-voltage circuits frequently operate in millivolt ranges.
When are kilovolts used?
Kilovolt and higher ranges are common in power transmission, substations, and high-voltage engineering.
Are voltage conversions multiplicative?
Yes. SI prefix voltage conversions are purely multiplicative with no additive offsets.
