calculator

This page describes a calculator that converts power to Vrms, Vpeak, and Vp-p (peak-to-peak voltage). It also includes a Watt to dBm conversion since the primary calculator uses dBm as its input.

Calculator 1 : Power in dBm to volts (rms) and Volts (peak) conversion

Inputs

Outputs

This calculator requires power input in dBm. If you have power in Watts, use Calculator #2 below to convert to dBm first.

EXAMPLE #1:

  • INPUT: Power in dBm = 40
  • OUTPUTS:
    • Vrms = 22.360 Volts
    • Vpeak = 31.618 Volts
    • Vp-p = 63.236 Volts

Power to Vrms, Vpeak, Vp-p Conversion Formula or Equation

The following equations are used for the Power to Vrms/Vpeak/Vp-p conversion:
