Using the Widmark formula, as breath alcohol testing machines do internally, and mechanically, you can calculate the anticipated blood alcohol level one would expect from consuming a certain amount of beer, wine, or hard liquor. One can also calculate how many drinks of different types of intoxicant, it would take to elevate one’s blood alcohol level to a given number. Constants are built into this well-accepted formula, to account for physiological differences between men and women, and between heavier and thinner people.
Rather than drag you through a complex mathematical formula, I am instead providing a link below, which should give you a quick approximation as to the blood alcohol level you can expect from drinking various amounts of beer, wine, or spirits.
