In an inverting op-amp circuit for which the gain is −4 V/V and ...
Given by the ratio of the feedback resistor (Rf) to the input resistor (Rin), the gain can be calculated using the following formula:

Gain (A) = -Rf / Rin

The negative sign indicates that the output signal is inverted compared to the input signal. The gain magnitude is determined by the values of Rf and Rin.
