Using the alcohol units calculator

The calculator estimates alcohol units based on the type of drink, the amount you drink, and the alcohol by volume (ABV). You can use it to calculate the units in a single drink or to add up units across a day or a week.

Some people find it helpful to use the calculator occasionally, rather than every time they drink, to get a clearer sense of how strong their usual drinks are.

What is an alcohol unit?

In the UK, one unit of alcohol is defined as 10 ml, or 8 grams, of pure alcohol. This definition is used across health services to help describe alcohol intake in a consistent way.

Because drinks vary widely in both size and strength, the number of units in a drink is not always obvious. A glass of wine, a pint of beer, or a mixed drink can each contain very different amounts of alcohol depending on how they are served.

UK alcohol guidelines

Current UK guidance advises that adults should not regularly drink more than 14 units of alcohol per week. This applies to both men and women.

Spreading drinking over several days and including alcohol-free days is safer than drinking the same amount in one or two sessions. Drinking within these limits does not make alcohol risk-free, but it reduces the likelihood of long-term health problems.

Why alcohol units matter

Alcohol affects many parts of the body. Regularly drinking more than recommended limits increases the risk of conditions such as:

• مرض الكبد.

• بeart disease.

• سtroke.

• سome cancers.

• مental health problems.

It can also affect sleep, concentration, and energy levels, and increase the risk of accidents.

Tracking units can help highlight patterns of drinking that may not feel excessive but still increase health risk over time.

Understanding your result

The calculator shows how many units are in your drinks and how this compares with weekly guidance. If the total is higher than expected, this does not automatically mean there is a problem with alcohol use.

Many people are surprised to find that their usual drinks are stronger or larger than they realised. Small changes, such as choosing lower-strength drinks, reducing serving sizes, or having more alcohol-free days, can make a noticeable difference to weekly intake.

Alcohol strength and drink size

Alcohol units depend on both strength and volume. Drinks served at home or in pubs can vary considerably.

Wine glasses are often larger than a standard serving, craft beers and IPAs tend to be stronger than traditional lagers, and cocktails may contain more than one measure of spirits. Using the calculator helps account for these variations.

When to think about cutting down

It may be worth reviewing alcohol intake if drinking regularly exceeds 14 units per week, affects sleep or mood, or feels hard to control. Some people also choose to cut down for short periods to see how alcohol affects their wellbeing.

Support is available if cutting down feels difficult.

When to seek further help

Speaking to a healthcare professional may be helpful if there are concerns about alcohol use, if cutting down feels hard, or if alcohol is affecting physical or mental health.

Symptoms such as cravings, loss of control, or withdrawal when not drinking should always be checked.

الأسئلة الشائعة

Does everyone need to follow the same limits?

The 14-unit guideline applies to most adults, but some people should drink less or not at all, depending on health, pregnancy, or medication.

Is it safe to drink all my units at once?

Drinking a large amount in a short time increases the risk of harm, even if weekly totals are within guidelines.
