Here are the charts -
It's more typical for the average 180 pound man to be around 0.02% after 1 drink, and for the average 140 pound woman to be around 0.03% after 1 drink. In the case of these charts, "One drink is 1.25 oz. of 80 proof liquor, 12 oz. of beer, or 5 oz. of table wine."
Nice link.
I don’t think the chart is accurate based on my experience but I think its better to be conservative if you’re going to be driving.
