Question

Is there a way to calculate the % of alcohol in body with respect to the amount of alcohol which is being consumed?

I mean lets say someone is 70Kg and is drinking 2 beers which are 5% each ( each beer 250ml ), is there a way to know what will be his alcohol % in his body after lets say 1 hour?
