Voltage Unit Information
+About Volts & Millivolts
Voltage is the electrical potential difference between two points, measured in volts (V).
1 volt (V) = 1,000 millivolts (mV)
1 millivolt (mV) = 0.001 volts (V)
Common Voltage References
Application
Typical Voltage
Neural Signals
0.1 - 100 mV
ECG/EKG Signal
0.5 - 5 mV
AA Battery
1.5 V
USB Port

Examples
5 Volts to Millivolts:
5 V × 1,000 = 5,000 mV
500 Millivolts to Volts:
500 mV ÷ 1,000 = 0.5 V
1 V = 103 mV = 1000 mV
or
1 mV = 10-3 V = 0.001 V
Volts to millivolts formula
The voltage V in millivolts (mV) is equal to the voltage V in volts (V) times 1000:
V(mV) = V(V) × 1000
Example
Convert 3 volts to millivolts:
V(mV) = 3V × 1000 = 3000 mV
