dBm to dBµA Calculator is used to convert any power level in dBm to the current value in dBµA using the power (in dBm) and the characteristic impedance Z (in ohms) of the system. 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 is used in EMC-conducted emission testing for measuring conducted emission current levels when applying 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 used in wireless and RF applications to express signal power levels.

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