What is dBV to dBm Calculator?  

dBV to dBm Calculator is used to convert any voltage value in dBV value to power value in dBm, using the voltage value (in dBV) and the system impedance Z (in ohms) value 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).  
• dBm (decibel-milliwatts)- the decibel unit for measuring power levels with reference to one milliwatt (1 mW). The dBm unit is typically used in wireless and RF applications to express signal power levels.  
• Z- System impedance in ohms.  

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