- 1 mV = 0.001 V
- 5 mV = 0.005 V
- 10 mV = 0.01 V
- 25 mV = 0.025 V
- VoltsV
- MillivoltsmV
- VoltsV
- MillivoltsmV
How it’s calculated
V = mV × 0.001
- Multiply the value in millivolts by 0.001.
- To go back, divide by 0.001 (or multiply by 1000).
- 1 mV = 0.001 V · 1 V = 1,000 mV
Quick examples
1 millivolt = 0.001 volts · 1 V = 1,000 mV
- 1 millivolt = 0.001 volts
- 5 millivolts = 0.005 volts
- 10 millivolts = 0.01 volts
- 25 millivolts = 0.025 volts
- 100 millivolts = 0.1 volts
