What basic RF math formula should be used as a baseline to convert an RF...

In wireless RF mathematics, conversion between dBm (a logarithmic unit) and milliwatts (a linear power unit) is a foundational skill. The correct formula to convert a known dBm value to its equivalent in milliwatts (mW) is:

mW = 10^(dBm / 10)

This formula expresses the inverse of converting from mW to dBm (which is: dBm = 10 × log10(mW)).

For example:

0 dBm = 10^(0/10) = 1 mW (which is a known reference point in RF)

This allows for easy conversion of power levels in wireless design, helping to determine link budgets, path losses, and power limits.

Incorrect options:

A is a correct statement (0 dBm = 1 mW), but not a conversion formula.

B and C are incorrect algebraically and do not represent logarithmic conversion principles.
