Breathalyzer measurement units

In Lithuania, blood alcohol concentration (BAC) is measured in promille (‰) — grams of pure alcohol per litre of blood. For example, 1 ‰ means about 1 gram of alcohol per litre of blood, so 2.5 ‰ is roughly 2.5 g/L. Breath alcohol is measured separately in mg/l of exhaled air.

The same value looks different in other countries, so the conversions are worth knowing: BAC % (used in the US, UK and Australia) equals promille ÷ 10, so 0.4 ‰ = 0.04 %; medical lab reports sometimes use mg/dL, where 100 mg/dL = 1 ‰. The general legal limit in Lithuania is 0.4 ‰ (0.2 ‰ for novice and professional drivers), so being able to read the figure in any unit helps. Our calculator always shows the result in promille.

Applied margin of error

Breathalyzers typically used by police record a margin of error of 5% or less. For instance, if the breathalyzer showed 0.43 promilles (‰), applying the margin of error the promille count could decrease or increase by 0.0215 promilles (‰), which is 4.515‰ or 4.085‰, and that would not help avoid liability, since Lithuania has a limit of 0.4‰.

How long after drinking can you drive

Each person's intoxication after drinking the same amount of the same beverage can be different and sobering up also varies. This depends on a person's body mass, gender, food consumption and overall health condition. However, calculating the average over 3 hours, with an average metabolic rate, the alcohol contained in 500 ml (5%) of beer or 50 ml of vodka or 200 ml of wine (about 12%) can typically be processed.

How long does it take for 1 promille of alcohol to be eliminated from the blood

The body eliminates alcohol slowly and at a fairly constant rate — about 0.12–0.20 ‰ per hour, handled almost entirely by the liver. Based on that rate, 1 ‰ takes roughly 5 to 8 hours to clear, depending on the person.

The exact speed depends on body weight, sex, liver health, food and how much was drunk, but the rate cannot be sped up — coffee, a cold shower, exercise or a big meal make no difference. Only time lowers the promille count. This is why residual alcohol the next morning is a common cause of drink-driving offences: someone who ends the night at 1.5 ‰ can still be around 0.5 ‰ by 8 AM. Use the calculator as an estimate and always leave a safety margin before driving.

How to sober up faster

No — this is a persistent myth. Alcohol is broken down almost entirely by the liver, at a fixed rate of about 0.1–0.15 ‰ per hour, and nothing speeds that up. Drinking water, coffee, a cold shower, exercise or a big meal do not lower your blood alcohol concentration.

Water is still worth drinking — it helps with the dehydration behind many hangover symptoms, so you may feel a little better — but it does not reduce the promille count or make you fit to drive. Coffee can make you feel more alert while you are still legally impaired, which is arguably more dangerous. The only thing that actually lowers your BAC is time. If you have been drinking, plan enough hours before driving, or do not drive at all.

Alcohol unit

According to the World Health Organization, a standard alcohol unit (SAU) contains 8 g or 10 ml (1 cl) of pure alcohol and can be calculated using the formula alcohol volume (ml) x strength in percent (%, e.g.: 0.05) x alcohol density (≈0.8 g/l) / 10 g. According to this, 500 ml of 5 percent strength beer contains 2 SAU, 750 ml of 12 percent strength wine 7 SAU, 500 ml of 40 percent strength drink 16 SAU.

Alcohol sale hours

In Lithuania, alcohol may only be bought by people aged 20 and over — one of the highest minimum purchase ages in the EU. Permitted retail sale hours are 10:00 to 20:00 on weekdays and Saturdays (including public holidays), and only 10:00 to 15:00 on Sundays.

Outside these hours shops and supermarkets may not sell take-away alcohol, although licensed bars, restaurants and cafés serving on the premises are exempt. These rules are part of Lithuania's strict alcohol-control policy, which also includes a near-total advertising ban. If you plan to drink and still need to drive later, remember the general limit is 0.4 ‰ (0.2 ‰ for novice and professional drivers) — check your level with the calculator before getting behind the wheel.
