Calculating BAC

Blood Alcohol Concentration (BAC) is a measure of the amount of alcohol present in your bloodstream. Knowing your BAC can be an essential tool in various situations, particularly when it comes to making responsible decisions. Whether you’re about to leave a bar or restaurant after a few drinks or facing charges for Driving Under the Influence (DUI), understanding BAC is critical.

When stopped for DUI, law enforcement may conduct field sobriety tests such as standing on one leg, walking heel-to-toe in a straight line, or following a light with your eyes. If the officer suspects that alcohol or drugs are impairing your abilities based on these tests, they may require further assessments like a breathalyzer test, blood test, or urine test to measure BAC.

What Is Blood Alcohol Concentration?

BAC reflects the percentage of alcohol in your blood. For example, if your BAC is 0.08%, it means there are 0.08 grams of alcohol for every 100 milliliters of blood. Consuming alcoholic beverages raises your BAC, with higher levels leading to greater impairment.

The legal BAC limit for adults in Erie County, Pennsylvania, and most other states, is 0.08%. For those under the legal drinking age, Erie County enforces a strict zero-tolerance policy for underage DUI. This means a BAC of 0.02% or higher results in an automatic DUI charge.

Factors That Impact BAC

Several factors can influence your BAC. Here’s a breakdown of the most important ones:

• Gender

Women generally have a higher BAC than men after consuming the same amount of alcohol. This is often due to the difference in body composition and physique, with women typically having less water in their bodies to dilute alcohol.

• Body Fat

A higher body fat percentage can lead to a higher BAC because fat tissue doesn’t absorb alcohol, allowing more of it to enter the bloodstream.

• Empty Stomach

Drinking on an empty stomach speeds up the absorption of alcohol, resulting in higher BAC levels. Eating before or while drinking can slow this process.

• Body Size

Smaller and lighter individuals tend to have a higher BAC than larger people for the same amount of alcohol because the alcohol has less body mass to distribute throughout.

Determining Your BAC

To estimate your BAC, it helps to understand the typical alcohol content of beverages. For instance, one standard drink equals the following:

• 5-ounce glass of wine (15-20% alcohol)
• 1.5-ounce shot of liquor (30-50% alcohol)
• 12-ounce beer (4-4.5% alcohol)

Drinks like a Long Island Iced Tea combine multiple liquors and can have higher alcohol percentages, around 22% in some cases.

To perform a basic BAC calculation, you can use Widmark’s Formula. Here’s how it works:

BAC = (ounces of alcohol consumed × 5.14 / weight in pounds × gender constant) – (.015 × hours since drinking began)

The gender constants used for the calculation are 0.66 for women and 0.73 for men.

Example

Imagine a 150-pound woman consuming two 12-ounce beers within two hours.

BAC = (1.20 × 5.14 / 150 × 0.66) – 0.03

BAC = (6.168 / 99) – 0.03

BAC = 0.032%

This BAC is under the legal limit of 0.08%, meaning she is not legally intoxicated. However, it’s still essential to assess overall well-being and safety before driving.

What to Do If Your BAC Is Too High

If you’ve calculated or tested your BAC and it’s above the legal limit, do not drive. You may risk severe legal repercussions, including fines, license suspension, or DUI charges. It’s crucial to comply with any law enforcement requests for a BAC test. Refusing a chemical or breath test in Erie County can lead to automatic license suspension and additional penalties.
