I'm not personally very familiar with the equations used, but you can find the equations in the, e.g., C:\Program Files (x86)\NREL\BEopt_2.7.0\Modeling\sim.py file. Two methods are used:
def get_infiltration_SLA_from_ACH50
def get_infiltration_ACH_from_SLA

The ACH50 value is first converted to SLA, and then to ACH.

Hope that helps.
