Millivolts (mV)
1 Volts (V) = 1000 Millivolts (mV)
How to convert Volts (V) to Millivolts (mV)?
Volts and millivolts are units of electrical potential (voltage). The relationship is:
- 1 V = 1000 mV
- 1 mV = 0.001 V
To convert Volts (V) to Millivolts (mV), multiply the value by 1000.
Formula: Millivolts (mV) = Volts (V) × 1000
Step-by-Step Calculation
- Take the number of Volts (V) you want to convert (e.g., 5).
- Multiply that value by 1000.
- The result is the value in Millivolts (mV). (Example: 5 V × 1000 = 5000 mV).
How to use this converter?
Enter volts (V) and instantly get millivolts (mV)—useful for electronics, sensors, and lab measurements.
Common Volts to Millivolts Conversions
Quick reference guide for common voltage values.
0.1 V = 100 mV
