What is dBV to dBW Calculator?  

dBV to dBW Calculator is used to convert any voltage level in dBV to the power value in dBW,  using the voltage value (in dBV) and system impedance Z (in ohms) entered by the user.  The calculator uses the following formula: 

Where,

• dBV (decibel-Volt)- the decibel unit for measuring voltage with reference to one Volt (1 V).  
• dBW (decibel-Watt)- the decibel unit for measuring power with reference to one Watt (1 W).  
• Z- System impedance in ohms. 

The dBV to dBW calculator helps to calculate the power value in dBW from voltage in dBV by inputting the voltage level (in dBV) and system impedance Z (in ohms). It quickly and accurately calculates dBW from dBV and impedance (Z). This calculator is a useful tool when you deal with EMC measurements, where precise measurement and analysis of signal strength are crucial.
