About results
Current BAC

Your Current BAC shows your estimated blood alcohol concentration right now as a percentage. This number reflects how much alcohol is in your bloodstream and is used to assess impairment.

Legal limit

In the United States and Canada, the standard legal driving limit for fully licensed adults is 0.08 % BAC. Exceeding this can result in DUI/DWI penalties, including fines and license actions.

Elimination rate

This shows the assumed average rate your body metabolizes alcohol — typically ~0.015 % BAC per hour. It’s an estimate of how fast your BAC decreases over time.

Standard Drinks

The number of Standard Drinks represents the approximate number of typical servings you’ve consumed (e.g., one beer, glass of wine, or shot), based on local standards for drink size.

Pure Alcohol

This is the amount of pure alcohol (in ounces) your body has absorbed so far, giving you a measure of total alcohol consumed.

Time vs. Sobriety Table

The table lists how your BAC is expected to change with each hour passed — and when a Start time of drinking is provided, it aligns these estimates with the exact time of day you began drinking. For example, if you started at 6:00 PM, the column will show your projected BAC at 6:00 PM (Now), 7:00 PM (1h), 8:00 PM (2h), etc., so you can clearly see when your BAC is likely to cross legal and safer thresholds as the day progresses. Icons or status indicators show whether the level is safe for driving at those specific clock times, making it easier to plan your departure or rest period.

Sobriety Over Time Graph

A visual line chart plotting your estimated BAC decline over hours. It helps you see when your BAC drops below legal and safer levels.

How Alcohol Affects You

This reference table shows ranges of BAC and typical effects on your body and behaviour — from mild alertness changes to significant impairment at higher levels.

Legal limit reached in / Sober in / Peak BAC

These summaries give quick key estimates:

  • Legal limit reached in: the time until your BAC likely falls below the legal driving limit.

  • Sober in: total time until BAC reaches ~0.000 %.

  • Peak BAC: the highest BAC value recorded in the session.

Data used for calculations

Five factors that determine your result

Weight
Body weight determines how alcohol distributes in the body — more weight means a lower blood alcohol concentration.
Sex
Men and women metabolize alcohol at different rates because of differences in body water content.
Amount
The amount of pure alcohol consumed is the main factor that determines your BAC result.
Strength
A higher strength (%) means more ethanol in the same drink serving.
Time
The time of your first drink shows how BAC changes hour by hour and when you'll be sober again.

Tips for Responsible Drinking

Practical tips for safer drinking

Pace yourself
Stick to the "one drink per hour" rule – your liver needs time to process alcohol.
Eat before and while drinking
A solid meal slows alcohol absorption – an empty stomach raises BAC faster.
Drink water
After each alcoholic drink, have a glass of water – it reduces dehydration and health risks.
Don't drive
Even small amounts of alcohol impair reaction time. If in doubt, call a taxi or stay overnight.
