About this calculator

Convert volts to millivolts by multiplying by 1000. One volt equals 1000 millivolts. This conversion is common in electronics, sensor measurements, and biomedical applications where small voltages are measured.

Common examples

  • 1 V = 1000 mV
  • 0.5 V = 500 mV
  • 3.3 V = 3300 mV (logic level)
  • 5 V = 5000 mV (USB standard)
  • 12 V = 12000 mV (car battery)
