How to convert Millivolts (mV) to Volts (V)?
Millivolts and volts measure electrical potential. The relationship is:
- 1000 mV = 1 V
- 1 mV = 0.001 V
To convert Millivolts (mV) to Volts (V), divide the value by 1000.
Formula: Volts (V) = Millivolts (mV) ÷ 1000
Step-by-Step Calculation
- Take the number of Millivolts (mV) you want to convert (e.g., 500).
- Divide that value by 1000.
- The result is the value in Volts (V). (Example: 500 mV ÷ 1000 = 0.5 V).
How to use this converter?
Enter millivolts (mV) and instantly get volts (V)—useful when matching sensor outputs to voltage ranges.
Common Millivolts to Volts Conversions
Quick reference guide for common values.
50 mV = 0.05 V
100 mV = 0.1 V
250 mV = 0.25 V
500 mV = 0.5 V
750 mV = 0.75 V
1000 mV = 1 V
1500 mV = 1.5 V
3300 mV = 3.3 V
5000 mV = 5 V
12000 mV = 12 V
Tip: Keep decimals clean
Because 1000 mV = 1 V, dividing by 1000 usually gives a neat decimal result.

Frequently Asked Questions
How do I convert mV to volts?
Divide millivolts by 1000 to get volts.
How many volts is 500 mV?
500 mV equals 0.5 V.
How many volts is 3300 mV?
3300 mV equals 3.3 V.
Is this conversion exact?
Yes—milli means one-thousandth, so 1000 mV is exactly 1 V.
Why do electronics use mV?
Small signals (like sensor outputs) are often easier to measure and describe in millivolts.
