I-Calculator ye-Alcohol yegazi (BAC)
Linganisa ukuthambekela kwe-alcohol emlonyeni kusuka emidlalweni, ubunzima besikhumba kanye nesikhathi.
Iziphetho zivuselelwa uma ubhala.
Malunga nale khadi
A blood alcohol content (BAC) calculator estimates the alcohol in your bloodstream using the Widmark formula, from the number of standard drinks, your body weight and sex, and the time since your first drink. It is an educational estimate only — many factors change real BAC, so never use it to decide whether to drive.
Widmark works out grams of alcohol, spreads them through the body water, and subtracts what has already been metabolised: BAC% = alcohol grams ÷ (body-weight grams × r) × 100 − 0.015 × hours, where r is about 0.68 for men and 0.55 for women. For a 75 kg man who has had 3 US standard drinks (3 × 14 = 42 g of alcohol) over 1 hour, that is 42 ÷ (75,000 × 0.68) × 100 − 0.015 = roughly 0.067% — near, but under, the common 0.08% legal limit.
The tool also shows a rough time to sober up, dividing your current BAC by the 0.015% per hour the body clears. That elimination rate is fixed — coffee, water, food and a cold shower do not speed it up. Real BAC depends on drink strength, food, hydration, medication and individual metabolism, so this is for education only: if you have been drinking, do not drive.
Imibuzo ebuzwa kaningi
Yini i-formula ye-Widmark?
BAC% = (gramu ye-alcohol ÷ (isisindo se-gramu × r)) × 100 − 0.015 × amahora, lapho i-r iyinani lokuhlukaniswa (ngo-0.68 kubantu abadala no-0.55 kubantu abadala) futhi 0.015 yiphesenti le-alcohol elahlekile ngehora.
Ingabe lokhu kulungile ngokwanele ukucabanga ukuthi ngizokwazi ukushayela?
Akunalutho. I-BAC esemthethweni ixhomekeke ekudleni, ekuhlanzeni, ekudleni, ekudleni okuqinile kanye nokudla okuthile, futhi ukulinganiselwa kungase kube lula. Uma uphuze, ungashayeli — le thuluzi liyimfundo kuphela.
Ngabe kuzothatha isikhathi esingakanani kuze kube yilapho i-BAC yami ibuyela ku-zero?
Isikhumba sihlanza i-alcohol ngo-0.015% ngehora ngaphandle kokuphuza ikhofi, amanzi noma ukubhukuda okubandayo. I-calculator ihlukanisa i-BAC yakho yamanje ngaleyo silinganiso ukulinganisela isikhathi sober-up.
Ingabe kudinga iziphuzo eziningi ukufinyelela ku-0.08?
Kuxhomekeka kusisindo, ucansi kanye nesikhathi. Umuntu oneminyaka engu-75 ubudala, oneminyaka engu-3-4 ubudala, utshwala olujwayelekile olungenalutho, luzofinyelela ku-0.08%, kodwa lokhu kulinganiselwa kuphela — awukwazi ukuwusebenzisa ukucabanga ukuthi ulungele ukushayela.
Ingabe utshwala luhlala isikhathi esingakanani esimisweni sakho?
BAC iphansi ku mayelana 0.015% ngehora, ngakho 0.08% izinga ithatha cishe amahora amane ukufinyelela zero. Akukho lutho ukhawulela ukususwa - hhayi ikhofi, amanzi, ukudla noma ishawa.
Yini ebalwa njenge-iwayini elisha?
E-US, isiphuzo esijwayelekile siwu-14 g we-alcohol ohlanzekile — i-12 oz beer, i-5 oz wine noma i-1.5 oz ye-spirits. Iyunithi yase-UK yi-8 g; hlela i-grams-per-drink field ukuze ifane nesimo sezwe lakho.
Kungani isondo lishintsha ukulinganiselwa?
I-Widmark r factor iphansi kubantu besifazane (imalunga ne-0.55 versus 0.68 kubantu besifazane) ngenxa yezinhlobonhlobo zokusakazwa kwamanzi emzimbeni, ngakho-ke iziphuzo ezifanayo zivame ukukhiqiza i-BAC ephezulu kubantu besifazane.
