A typical week
Pint of beer or cider
2.3 units each, 9.1 a week
Standard glass of wine
2.1 units each, 6.3 a week
Check the label for strength. Wine is often 13 to 14.5%, and craft beers can be 6% or more, which moves the total a lot.
A week
15.4 units
1.4 over the UK low-risk guideline of 14
14 g of alcohol each
A week, before mixers or sugar
The UK guideline is not a safe amount: it is the level at which the risk stays low, spread over three or more days rather than saved for one or two. US dietary guidance is set per day instead: up to two drinks a day for men and one for women.
A calculator answers once. If you want this number to move over months, that needs a record: a free habit tracker that shows the whole month on one screen.
Track it as a habitA UK unit is 10 millilitres, or 8 grams, of pure alcohol. The units in a drink are its volume in millilitres times its strength as a percentage, divided by 1,000. A pint of 4% beer is 568 times 4 over 1,000, which is 2.3 units.
The US counts standard drinks instead, each holding 14 grams of alcohol, so one US drink is about 1.75 UK units. The page shows both, because a lot of confusion about drinking guidance comes from mixing the two up.
The presets use common strengths, but check your own labels. Plenty of wines are 13.5 or 14%, not 12, and craft beers regularly run 5 to 7%. Two points of strength on a bottle of wine is about a unit and a half, every bottle. Pour sizes drift too: a home glass of wine is often closer to 250 ml than 175.
The UK Chief Medical Officers' guideline, published in 2016, is not to drink more than 14 units a week on a regular basis, spread over three or more days. It is the level at which the risk stays low. It is not a safe amount or a target, and the guidance says so.
This page will not tell you whether your number is a problem. If the total surprises you, the practical first step most people find useful is a couple of alcohol-free days a week, tracked, so you see whether they happen.
Pick from the list, then use plus and minus to set how many.
Both are editable. Labels beat presets.
In UK units, US standard drinks, grams and calories.
About 2.3 units in a pint of 4% beer or cider, and about 3 in a pint of 5.2% strong beer.
A 175 ml glass of 12% wine is 2.1 units. A 250 ml glass is 3 units. At 14% strength, add about a sixth.
The UK low-risk guideline is up to 14 units a week, spread over three or more days. US dietary guidance is set per day: up to two drinks for men and one for women.
No. The page works it out in your browser and nothing is sent or saved.
A calculator tells you where you are once. If the thing you actually want is to keep something up, that takes a record rather than a result.
