Drink Strength Comparison Calculator | The BAC Calculator

LABEL COMPARISON TOOL
Compare two labelled drinks by container size and ABV. The result shows pure alcohol, standard-drink context and alcohol-only calories—not impairment, BAC, or driving fitness.
Container size and number of servings also change the total alcohol amount.
DRINK STRENGTH COMPARISON
Use the volume and ABV printed on the label. Results are educational amount comparisons only.
The comparison shows amount, not personal effect. Food, timing, body factors and many other variables are not part of this tool.
Do not use an alcohol amount to decide whether to drive. If alcohol is involved, choose a sober way home.
For each label, we calculate volume in ml × ABV as a decimal × 0.789 g/ml. We then show the difference in grams, the selected country reference and alcohol-only calories. A larger or stronger container can contain more alcohol even when the drinks appear similar.
Two drinks can have different volumes and ABVs, so a percentage alone is not enough to compare the alcohol they contain. This tool is designed for reading labels and understanding reference units. It does not measure BAC, impairment, tolerance, health risk or legal status.
