Track drinks, BAC estimates, calories, cost, and hydration. Review weekly habits and compare serving sizes. Make informed choices with clear math and practical summaries.
| Example | Weight kg | Hours | Drink Mix | Session Standard Drinks | Estimated BAC |
|---|---|---|---|---|---|
| Example A | 70 | 2 | 2 beers at 330 mL and 5% | 1.86 | 0.0138 % |
| Example B | 80 | 3 | 3 wines at 150 mL and 12% | 3.04 | 0.0303 % |
| Example C | 65 | 2.5 | 2 spirits at 45 mL and 40% | 2.03 | 0.0121 % |
Pure alcohol mL = Serving mL × ABV ÷ 100 × Count.
Alcohol grams = Pure alcohol mL × 0.789.
Standard drinks = Alcohol grams ÷ 14.
Calories = Alcohol grams × 7.
Estimated BAC = ((Alcohol grams ÷ (Weight kg × 1000 × r)) × 100) − (Metabolism rate × Hours).
Hydration target = Standard drinks × 250 mL.
Weekly spend = Weekly standard drinks × average cost per standard drink.
The constant r is the body water factor. This tool uses 0.73, 0.66, or 0.70 by default.
Enter body details first. Add session timing and water intake. Fill the beverage rows with serving size, ABV, count, and price.
Then enter weekly standard drinks for each day. Press Calculate. The summary appears above the form, followed by the beverage table and graph.
Use CSV for spreadsheet review. Use PDF for a saved report. Treat every number as an estimate, not a legal or medical result.
It estimates alcohol grams, standard drinks, calories, cost, hydration target, and BAC. It also summarizes weekly intake with projections.
No. It is only an estimate. Food, medications, age, health, sleep, and drink timing can change real BAC significantly.
Standard drinks help compare beer, wine, and spirits on a common alcohol basis. They are useful for weekly tracking and budgeting.
Water does not cancel alcohol, but tracking water can support awareness. This tool uses a simple session target for planning.
No. Never use this estimate to decide whether driving is safe. Use safer choices and avoid driving after drinking.
It is a Widmark-style factor that adjusts alcohol distribution by body composition. You can use the default or enter a custom value.
Alcohol contains energy. Tracking calories helps users understand how drinking affects nutrition goals, weight management, and weekly totals.
No. It is for education and self-monitoring only. Seek medical or counseling support for health, dependence, or safety concerns.
