1. Convert to base units
volts = input value x input unit factor
Every supported voltage unit is stored as a factor relative to volts.

Common conversions
Useful voltage conversion factors
| Conversion | Factor | Typical use |
|---|---|---|
| Volts to millivolts | mV = V x 1000 | Electronics and sensor signals |
| Millivolts to volts | V = mV / 1000 | Circuit calculations |
| Kilovolts to volts | V = kV x 1000 | Power distribution and insulation |
| Microvolts to millivolts | mV = uV / 1000 | Low-level instrumentation |
| Megavolts to kilovolts | kV = MV x 1000 | High-voltage engineering |
| Gigavolts to volts | V = GV x 1,000,000,000 | Physics-scale examples |
How it works
Voltage conversion method
2. Convert to target units
target value = base value / target unit factor
The selected result and table values are calculated from the same base value.
3. Check precision
rounding depends on scale
Very small and very large values use compact scientific notation to stay readable.
