Track your alcohol consumption with this Canada-specific calculator. Learn about standard drinks, safe limits, and how to monitor your intake.

How to Use This Calculator

This calculator helps you estimate your alcohol consumption based on standard drinks and your body weight. Follow these steps:

Enter the number of standard drinks you've consumed
Select your gender
Enter your body weight in kilograms
Click "Calculate" to see your estimated blood alcohol concentration (BAC)

The calculator provides a visual representation of your BAC level compared to legal limits in Canada.

Formula Used

BAC = (A × 5.14 / W × r) - (0.015 × H) Where: A = Total alcohol consumed (grams) W = Body weight (kg) r = Alcohol distribution ratio (0.68 for men, 0.55 for women) H = Time since drinking started (hours)

This formula estimates your blood alcohol concentration based on standard drink measurements and your body composition.

Canadian Alcohol Guidelines

In Canada, the legal drinking age is 19. The government recommends:

No more than 2 standard drinks per day for women
No more than 3 standard drinks per day for men
No more than 10 standard drinks per week

A standard drink is defined as:

12 oz (355 mL) of beer (5% alcohol)
4 oz (120 mL) of 80-proof distilled spirits
5 oz (150 mL) of wine (12% alcohol)

Worked Examples

Example 1: Male Consumer

A 70 kg man drinks 3 standard drinks (about 17 grams of pure alcohol) in one hour. His BAC would be approximately 0.08%.

Example 2: Female Consumer

A 60 kg woman drinks 2 standard drinks (about 10 grams of pure alcohol) in one hour. Her BAC would be approximately 0.05%.

Note: These examples use simplified calculations. Actual BAC can vary based on individual metabolism and other factors.
