Volts to dBµA Calculator is a useful tool to convert any RMS voltage value in V to a current value in dBµA, using the RMS voltage (V) and the system impedance Z (in ohms) value entered by the user. The calculator uses the following formula: 

Where, 

Vrms - Represents the root–mean–square value of the electrical signal in Volts.
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 Volts to dBµA calculator helps to calculate the current value in dBµA from Voltage value (V) by inputting the RMS voltage level (in V) and system impedance Z (in ohms). The calculator quickly and accurately calculates dBµA from RMS Voltage (V) and impedance (Z). This calculator is a useful tool for engineers deal with EMC measurements and electronics calculations.
