What is 0.08 As a Percent?

When you’re out having drinks with friends, you don’t think about the effects of alcohol in terms of numbers like .08 percent BAC (blood alcohol content). But that number is one that often comes up when it comes to whether or not you can drive your car. Let’s take a look at what 0.08 percent really means so you can make an informed decision the next time someone suggests going out after work or on the weekend.

A Review of Drinking Limits

Averaging your blood alcohol content (BAC) over an hour or more may give you a different picture of how much you’ve actually had to drink than looking at your single BAC at any given time, explains The National Institute on Alcohol Abuse and Alcoholism (NIAAA). And when it comes to something as potentially dangerous as alcohol, accuracy counts. To calculate average BAC, take your weight in pounds and divide it by 2; then multiply that number by .0185—this works out to be .75 percent for someone who weighs 200 pounds.

How Much Alcohol Is in Beer?

Beer is made from yeast-fermented malt and flavored with hops, although some breweries add other grains to create different types of beer, such as stout or porter. The alcohol content of beer depends on what type you drink: Lager typically contains between 3 and 6 percent alcohol by volume (ABV). Most ales have an ABV of 4 to 7 percent, while stouts can have up to 8 percent ABV; some beers like imperial stouts even reach 12 percent or more.

Example Drinking Levels

This standard drink size has changed over time, from 3 ounces in an 18th-century English recipe to today’s 5-ounce standard across all U.S. recipes (except for wine and malt beverages). In general, though, one drink equals 12 ounces of beer; 8 ounces of malt liquor; 6 ounces of wine; or 1.5 ounces (one-shot) of 80-proof distilled spirits (or liquor). That works out to be just over two servings per container, but keep in mind that we’re talking standard serving sizes — you might get more than two servings if your drink comes in a larger bottle or if it contains extra shots on top of what’s listed on its label.

What is 0.08% as a Percent of Blood Alcohol Level?

Most adults know that it’s illegal to drive while intoxicated, but they may not know what exactly intoxicated means. In many states, having a blood alcohol content of .08% or higher can result in penalties for driving under the influence (DUI). But just how much does 0.08% represent as a percentage of your blood alcohol level? A person with a BAC of .08 has 80 milligrams of alcohol in 100 milliliters of blood. Here’s how to calculate that figure

How Can I Tell if I’m Drunk?

Calculating Blood Alcohol Content (BAC) is an excellent way to tell if you’re in danger of getting a DUI, or if you’ve gotten past that point already. The math isn’t too tricky: A BAC of .08 percent means that there are .08 grams of alcohol per 100 grams of your blood; conversely, there are 100 grams of alcohol per 1,000 grams of blood. It takes only two drinks to reach 0.04 BAC (four drinks to reach 0.1). Most experts recommend that you stop drinking once your BAC reaches 0.05 percent, and one drink will raise your BAC by about .02 percent—so it takes just three drinks to go from sober to legally drunk in many states.

How Does Smoking Affect my BAC Level?

When it comes to alcohol, a drink can mean anything from 1.5 ounces of hard liquor to five ounces of wine or 12 ounces of beer, but one thing is clear—the more you drink, the higher your blood alcohol concentration (BAC) level will be. If you’re trying to find out what does .08 percent BAC means, we’ve got an answer for you. But keep in mind that there are many other factors that affect BAC levels such as gender and weight along with how fast you consume alcohol and whether or not the food was consumed at all. Just like there’s no simple way to determine how much an individual weighs without actually weighing them, there’s no magical formula for calculating your own BAC level based on personal information alone.

How Can I Avoid Being Over the Limit?

With proper planning, it’s easy to avoid any penalties due to being over the limit in blood alcohol content (BAC). If you’re approaching your limit, you can slow down and rely on alternative transportation such as Uber or Lyft. Some states even have taxi services that are connected with government-sanctioned BAC tracking; if you call one of these taxi companies, they will drive slowly around until your BAC reaches 0.00 before they take you home so that no penalties apply to your license or criminal record (not all areas offer these special services though). You can also plan to have an additional sober driver just in case; it may be worth investing in some Uber gift cards for those emergencies too!

Should You Take a Breathalyzer Test?

If you’re stopped for drunk driving, one of two things might happen: either you or your attorney will ask for a chemical test of your blood or breath to be done; or, if neither of you asks for it and there’s no need to have one done, in some states law enforcement can require that you take one (even if they don’t have any reason to suspect that you are driving while intoxicated). If they do so, can they make you take one? Should you agree to take one just because an officer asked and he seems like he’s just trying to do his job?


So, what is 0.08 as a percent? While it might seem like a question that can be quickly answered, you’ll be shocked to learn just how long and complicated of an answer it really takes to accurately respond to that question. There are so many factors at play in determining what that percent number actually means for someone who’s had too much to drink and it’s important for drivers (and for those close to them) to understand those factors so they know when it’s time not just to stop drinking but also time to stop driving, period. If you have questions about what’s considered too much alcohol or if you believe someone around you may have driven while intoxicated, don’t hesitate asking us!
