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

Where, 

I - Represents the electrical signal current in Amps.
 dBm (decibel-milliwatts) is the decibel unit for measuring power levels with reference to one milliwatt (1 mW). The dBm is a convenient unit; used in radio, audio applications, and other RF applications to measure signal strength.

Z- System impedance in ohms.
The dBm to Amps calculator helps to calculate the current (in A) from power (in dBm) by inputting the power value (in dBm) and system impedance Z (in ohms). The calculator quickly and accurately calculates current (A) from dBm and impedance (Z). This calculator is a useful tool in wireless and RF applications as well as in EMC calculations.
