[Females] AC = (BAC * BW)/(1.51* % Ethanol)

Based upon Proof:
[Males] AC = (BAC* BW)/(0.61 * proof)
[Females] AC = (BAC * BW)/(0.75 * proof)

Time factor:
Added to this is 20 mg/dL/hr x hrs since ethanol is consumed.

Where,
AC - Alcohol consumption
BAC - Blood alcohol concentration in mg/dL
BW - Body weight in kg.
