If the pitch is 0.03125"/rev and the spindle is 100RPM
then the actual feedrate is 3.125"/min
The main query should be :"what is the code that is posted ?"
if output is G94
then the output feedrate should be F3.125
or
if the code G95 is stated
then F0.03126 sould be output
Hopefully there is a G94 before the next tool to set the feedrates back to feed per minute
