What is blood alcohol content (BAC)?

BAC is the percentage of alcohol in your bloodstream, expressed as grams of alcohol per 100 mL of blood. It rises with each drink and falls as your liver metabolizes alcohol over time, and it is the standard measure used in legal driving limits.

How does the BAC calculator estimate my level?

It uses the Widmark formula, factoring in your weight, sex, number of standard drinks, and time elapsed. Alcohol is removed at roughly 0.015% BAC per hour, so the tool also estimates when you would return to zero. Results are estimates only.

Is the calculated BAC accurate enough to drive?

No. Estimates can differ significantly from a breathalyzer due to food, hydration, medications, and individual metabolism. In many places the legal driving limit is 0.08%, but impairment starts well below that. Never use a calculator to decide whether you are safe to drive.

Kalkulačka obsahu alkoholu v krvi (BAC)

Tato kalkulačka používá klasický Widmarkův vzorec k odhadu obsahu alkoholu v krvi (BAC) z vaší tělesné hmotnosti, pohlaví, počtu standardních nápojů a hodin od prvního nápoje, přičemž zohledňuje alkohol, který vaše tělo již metabolizovalo (přibližně 0,015 % za hodinu). Odhaduje také, jak dlouho potrvá, než budete střízliví. Skutečná BAC se liší podle jídla, hydratace, léků a individuálního metabolismu, takže výsledek berte pouze jako hrubé vodítko a po požití alkoholu nikdy neřiďte.

Pouze hrubý odhad (Widmarkův vzorec). Mnoho faktorů mění skutečnou BAC. Po požití alkoholu nikdy neřiďte — toto není právní ani lékařská rada.
