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

Where, 

W – Electrical signal power in Watts (W)
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 employing the RF current probe method.

Z- System impedance in ohms.
The dBµA to Watts calculator helps to calculate the power in Watts from the current value in dBµA by inputting the current (in dBµA) and system impedance Z (in ohms). The calculator quickly and accurately calculates Watts from dBµA and impedance (Z). This calculator is a useful tool for engineers deal with EMC measurements and electronics calculations.
