Blood Alcohol Concentration is the most common parameter to assess your blood alcohol range. It is used to measure the amount of alcohol intoxication.



What Is Blood Alcohol Calculator?

It refers to the percentage of alcohol in the bloodstream, 30-70 minutes after drinking. It is the percentage of ethanol in the blood. Several factors influence blood alcohol levels, like volume and concentration of alcohol in a drink

How Is BAC Calculated?

  1. Check your weight in pounds or kilograms on a digital weighing machine.
  2. Estimate how much alcohol you have consumed in oz or ml.
  3. Estimate the % of alcohol in that particular drink by turning your bottle around to see the label.
  4. Estimate the hours you spent in drinking alcohol.

Your BAC will be calculated based on these parameters.

What Are Blood Alcohol Content (BAC) Levels?

Effects Based On Blood Alcohol Content

The effects of alcohol at various Blood Alcohol Concentration levels are listed below :

BACPhysical and Mental Effects
.01 – .03No apparent effects. Slight mood elevation. In California, you will test as legally impaired at .01% BAC if you are under 21. It is illegal to drive or ride a bike at this level.
.04 – .06Feeling of relaxation. A sensation of warmth. Minor impairment of reasoning and memory.
.07 – .09Mild impairment of balance, speech, vision, and control. In California, you will test as legally impaired at .08% BAC if you are over 21. It is illegal to drive or ride a bike at this level.
.10 – .12Significant impairment of motor coordination and loss of judgment. Speech may be slurred.
.13 – .15Gross impairment of motor control. Blurred vision and major loss of balance. Onset of dysphoria (anxiety and restlessness).
.16 – .20Dysphoria predominates. Nausea may appear. The person has the appearance of “sloppy drunk.”
.25 – .30Severe intoxication. Needs assistance walking. Mental confusion. Dysphoria with nausea and some vomiting.
.35 – .40Loss of consciousness. Brink of coma.
.40 and upOnset of coma. Likelihood of death due to respiratory failure.

How Long Does It Take To Get Alcohol Out Of Your System?

Alcohol is generally metabolized at a constant level, and many people experience its effects for a long time. The rate at which alcohol can get out of your system depends on the metabolism rate.

  • Approximately 10 % of the alcohol absorbed in the body is expelled through sweating, respiration, and urine. The rest is broken down internally. The liver plays a role in detoxifying it. It takes 1 hour to expel half an ounce of alcohol.
  • If the rate of elimination is 0.015% every hour, it will take almost 5 hours to flush out the entire alcohol.

How Much Alcohol Is Present In These Drinks?

  • Beer alcohol content: 4-7% Alcohol By Volume (ABV) with an average of 5%.
  • Vodka alcohol content: 40-95% ABV.
  • Average alcohol content of wine: 16-24 % ABV ( Fortified wine)
  • Rum alcohol content : 36-50% ABV
  • Whiskey alcohol content : 36-50% ABV

How To Get Alcohol Out Of Your System

  • Drink more water. The more water you drink, the more toxins are eliminated from the urine.
  • Remember to eat food while sipping on your drink.
  • Get enough sleep after consuming alcohol to give rest to your body.

Frequently Asked Questions

Is a BAC of 0.4% high?

total loss of consciousness, and difficulty walking and speaking.

What does a blood alcohol level of 50 mean?

In general, a blood alcohol level of 0.05–0.07% (50–70 mg/dL) represents euphoria and impaired motor skills.
