Aangaande hierdie sakrekenaar
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.
Dikwels gevra vrae
Wat is die Widmarkformule?
BAC% = (grams of alcohol ÷ (body-weight grams × r)) × 100 − 0.015 × hours, where r is the distribution ratio (about 0.68 for men and 0.55 for women) and 0.015 is the percent of alcohol eliminated per hour.
Is dit akkuraat genoeg om te besluit of ek kan bestuur?
Nee. Ware BAC hang af van voedsel, hidrasie, medikasie, drankkrag en individuele metabolisme, en die skatting kan maklik af wees.
Hoe lank totdat my BAC terugkeer na nul?
Die liggaam verwyder alkohol teen ongeveer 0,015 persent per uur ongeag koffie, water of 'n koue stort. Die sakrekenaar verdeel jou huidige BAC deur daardie tempo om die nugter-op tyd te skat.
Hoeveel drankies neem dit om 0,08 te bereik?
It depends on weight, sex and time. For a 75 kg man, roughly 3–4 standard drinks in an hour can approach 0.08%, but this is only an estimate — never use it to judge whether you are fit to drive.
Hoe lank bly alkohol in jou stelsel?
BAC falls at about 0.015% per hour, so a 0.08% level takes roughly five hours to reach zero. Nothing speeds up elimination — not coffee, water, food or a shower.
Wat is die belangrikste ding in een standaarddrankie?
In die VSA is 'n standaard drankie ongeveer 14 g van suiwer alkohol eribber' n 12 ozbier, 5 ozwyn of 1,5 oz. 'n VK-eenheid is 8 g; stel die gram-per-drinkveld om by jou land se definisie te pas.
Waarom verander seks die skatting?
The Widmark r factor is lower for women (about 0.55 versus 0.68 for men) because of differences in body-water distribution, so the same drinks tend to produce a higher BAC in women.
