1 mV = 0.001 V
1 Millivolt (mV) = 0.001 Volt (V).
If you want to reverse convert, use Volt → Millivolt. 1 V = 1000 mV. You can also explore the full Electric Voltage converter page for more cross conversions.
Conversion formula
Millivolt to Volt formula: value in V = value in mV × 0.001.
Volt to Millivolt formula: value in mV = value in V × 1000.
How to convert Millivolt to Volt
To convert Millivolt to Volt, multiply the value in mV by 0.001. This gives the result in V.
For example, 1 mV = 0.001 V and 10 mV = 0.01 V.
What is Millivolt?
Millivolt (mV): Small voltages, such as sensor outputs and voltage drops. 1 mV = 0.001 V.
What is Volt?
Volt (V): Potential difference that transfers one joule per coulomb. 1 V = 1 J/C = 1000 mV.
FAQ
How many volt are in 1 millivolt?
There are 0.001 V in 1 mV.
Why can conversion results differ slightly?
Check the unit definition and rounding. US and imperial measures can differ; rounding intermediate values can also change the final digits.
How do I convert millivolt to volt?
Multiply the value in mV by 0.001 to get the value in V.
Millivolt → other Electric Voltage units
- 1 millivolt → volt = 0.001 volt
