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

Where, 

dBµA (decibel-microampere) is the decibel unit for measuring current with reference to one microampere (1 µA). The dBµA unit finds usage in EMC-conducted emission testing for measuring conducted emission current levels when employing the RF current probe method.
dBm (decibel-milliwatts) is the decibel unit for measuring power levels with reference to one milliwatt (1 mW). The dBm unit is typically utilized in wireless and RF applications to express signal power levels.

Z- System impedance in ohms.
The dBµA to dBm calculator helps to calculate the power value in dBm from current in dBµA by inputting the current level (in dBµA) and system impedance Z (in ohms). The calculator quickly and accurately calculates dBm from dBµA 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.
