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.

Lesi sibali sisebenzisa ifomula yakudala ye-Widmark ukulinganisa izinga lotshwala egazini (BAC) ngokusuka esisindweni somzimba wakho, ubulili, inani leziphuzo ezijwayelekile namahora kusukela esiphuzweni sakho sokuqala, kubalwa notshwala umzimba wakho osuwugayile (cishe 0.015% ngehora). Sibuye silinganise ukuthi kuzothatha isikhathi esingakanani uze uphaphame. I-BAC yangempela iyahluka ngokudla, amanzi emzimbeni, imithi nendlela umzimba ogaya ngayo, ngakho thatha umphumela njengesiqondiso esinganembile kuphela futhi ungalokothi ushayele ngemva kokuphuza.

Isilinganiso esinganembile (ifomula ye-Widmark) kuphela. Izici eziningi zishintsha i-BAC yangempela. Ungalokothi ushayele ngemva kokuphuza — lokhu akukona iseluleko somthetho noma sezempilo.
