What Does This Mean For You?
One of the most common things we do without even thinking is counting how many drinks we have had. We do this to either brag or to make sure we feel comfortable to get behind the wheel of an automobile. As we all know .08 is the legal limit in Texas. So how can we calculate on our own whether we are over that limit?
One Drink Potential
A One Drink Potential is the maximum BAC that a person will reach after one drink. In order to calculate someone’s ODP, you will need the following information and a calculator:
- Gender (for males use .13; females use .11 in the calculation)
- Body weight in pounds
- Type of Drink (or alcohol content)
- Size of drink in ounces
For example, let’s say John is meeting some friends at a bar in Houston. John weighs 200 lbs. The calculation for a 200-pound male who drank one 12-ounce, 4.16% alcohol beer (Bud Light) is:
(12 oz. beer) X (.0416 alcohol content)
(200lbs) X (.13) = .499/26 = .019 per drink
What this means is that John, has a one-drink potential of .019. Further, the maximum BAC that John would reach after consuming the one Bud Light is .019.
While not an exact science, this calculation provides us with an idea of where an individual would be if they were subject to a blood alcohol test.
