dBm to Volts Conversion Calculator

This calculator helps you convert between dBm and volts. It calculates both RMS and peak voltage values.

The following calculator converts power to voltage, providing results in both RMS and peak units.

Power in dBm to Volts

EXAMPLE #1:

Input : Power in dBm = 10

Outputs :

• Volts in RMS = 0.707
• Volts peak-to-peak = 2.0
• Volts , peak = 1.0

dBm to Volts Conversion Formula

The following equation is used to convert dBm to volts:

In the formula, “Z” represents the impedance, and it’s typically taken as 50 Ohms.

• V peak-to-peak = V RMS * 2.8284
• V peak = V peak-to-peak / 2

Volts to dBm Conversion

This calculator converts voltage_rms to power in dBm.

EXAMPLE #2:

Input : Volts_rms = 0.707 Output : Power in dBm = 10
