Method and calculation

Convert voltage through the volt: value × source factor / target factor. Factors relative to volt: V = 1; mV = 0.001; µV = 0.000001; kV = 1000; MV = 1000000.

Inputs and settings

Voltage Converter accepts Value (minimum 0); From unit (V, mV, µV, kV, MV); To unit (V, mV, µV, kV, MV).

Worked example

Voltage Converter example — Value: 1; From unit: "V"; To unit: "mV". Computed output: { "value": 1000, "unit": "mV", "baseValue": 1, "baseUnit": "volt" }

Output and limitations

Voltage is electric potential difference between two points. Millivolts are common for sensor signals, while kilovolts describe high-voltage equipment. Decibel-voltage units are excluded because their logarithmic references differ from the linear metric prefixes listed here.

Voltage Converter FAQs

How does Voltage Converter work?

Voltage Converter applies the following rule to your input: Convert voltage through the volt: value × source factor / target factor. The worked example on this page uses the same processor as the result button.

What should I check in Voltage Converter?

Voltage Converter has these boundaries: The voltage factors are fixed conversions. Unit labels specify the convention; no live data is fetched. Start by checking the value field against the units or format shown.

Can I try an example in Voltage Converter?

Voltage Converter provides this sample: { "value": 1000, "unit": "mV", "baseValue": 1, "baseUnit": "volt" }. Use the sample button to reproduce it, then replace the inputs with your own values.
