Vpp to dBm Calculator

This calculator can be used to convert between Peak-to-Peak Voltage and Power.

The formula to convert VPP to dBm is

PdBm = 10*Log10((1/Z)*(Vpp/(2√2))2)

The impedance Z, will also need to be specified (default value is 50 ohm)

The calculator also provides VRMS where

VRMS = Vpp/(2√2)
