Malunga nale Calculator
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 ebuza rhoqo
Yintoni ifomula yeWidmark?
I-BAC% = (igrams zealcohol ÷ (igrams zobunzima bomzimba × r)) × 100 − 0.015 × iiyure, apho i-r ithetha ukuba unikezelo lulingana (malunga ne-0.68 kubantu abadala ne-0.55 kubantu abadala) kwaye i-0.015 ithetha ukuba iipesenti zealcohol ezisuswa ngeyure.
Ingaba le nto ichanekile ngokwaneleyo ukuba ndigqibe ukuba ndiya kwazi ukuqhuba?
Akukho nto. Umgangatho opheleleyo we-BAC uxhomekeke kukutya, ukutya okunesondlo, imithi, uxinzelelo lokutya kunye nokusetyenziswa kwezinto eziphilayo, kwaye ubalo lunokucaca ukuba lungekho. Ukuba usele usela, musa ukuqhuba—le sixhobo sisetyenziswa kuphela ukufundisa.
Kuthatha ixesha elingakanani de i-BAC yam ibuye ibe yi-zero?
Iqulatho lisusa i-alcohol kwiqulatho elimalunga ne-0.015 yeepesenti ngeyure, nokuba utywala, utywala okanye utywala olubandayo. I-calculator ihlula i-BAC yakho yangoku nge-rate ukuze iqikelele ixesha lokuzimela.
Ithatha ixesha elingakanani ukusela ukufikelela kwi-0.08?
Oku kuxhomekeka kubunzima, kuhlobo lwesondo kunye nexesha. Kumfazi obunzima bakhe buyi-75 kg, ukutya okuqhelekileyo okuphakathi kweeyure ezi-3-4 kunokuthi kufike kwi-0.08%, kodwa oku kuqikelelwa kuphela—singayisebenzisi le nto ukugqiba ukuba ulungele ukuqhuba.
Ihlala ixesha elingakanani iwayini eluhlaza kwinkqubo yakho?
Umgangatho we-BAC uphantsi nge-0.015% ngeyure, ngoko ke umgangatho we-0.08% uthatha malunga neyure ezisixhenxe ufike kwisiqingatha. Akukho nto ikhawulezisa ukususwa kwe-BAC—akukho ikhofi, amanzi, ukutya okanye ukuhlamba.
Yintoni ebala njengesiselo esiqhelekileyo?
Kwi-US, isiselo esiqhelekileyo simalunga ne-14 g ye-alcohol ecocekileyo—i-12 oz ye-beer, i-5 oz ye-wine okanye i-1.5 oz ye-spirituality. Iyunithi ye-UK yi-8 g; misela i-grams-per-drink field ukuze ihambelane nolwazi lwelizwe lakho.
Kutheni umtshato utshintsha ubalo?
I-Widmark r factor iphantsi kumabhinqa (imalunga ne-0.55 xa kuthelekiswa ne-0.68 kumabhinqa) ngenxa yobubanzi bokusasazwa kwamanzi emzimbeni, ngoko ke iziselo ezifanayo zihlala zivelisa i-BAC ephezulu kumabhinqa.
