We’re supposed to be keeping an eye on how much we drink, but how many of us really know what a unit of alcohol is? With so many different drinks and glass sizes, from shots to pints – not to mention bottles – it’s easy to get confused about how many units are in your drink.
- The idea of counting alcohol units was first introduced in the UK in 1987 to help people keep track of their drinking.
- Units are a simple way of expressing the quantity of pure alcohol in a drink.
- One unit equals 10ml or 8g of pure alcohol, which is around the amount of alcohol the average adult can process in an hour.
This means that within an hour there should be, in theory, little or no alcohol left in the blood of an adult, although this will vary from person to person. The number of units in a drink is based on the size of the drink, as well as its alcohol strength.
men and women are advised not to drink more than 14 units a week on a regular basisspread your drinking over 3 or more days if you regularly drink as much as 14 units a weekif you want to cut down, try to have several drink-free days each week
14 units is equivalent to 6 pints of average-strength beer or 10 small glasses of lower-strength wine.
How many unit of alcohol do I drink?
Measuring units – Units provide a simple way for us to calculate the quantity of pure alcohol in a drink using its strength and size. One unit equals 10ml or 8g of pure alcohol. You can work out how much alcohol is in your drink – based on its strength and size – by using the following equation:
strength (alcohol by volume or ABV) x the volume of the drink (in millilitres) ÷ 1,000 = the total number of units in your drink
So to find the number of units in a pint of 4% ABV beer, calculate:
4 (ABV%) x 568 (ml) ÷ 1,000 = 2.3 units
or For a medium-sized glass of 13% ABV wine calculate:
13 (ABV%) x 175 (ml) ÷ 1,000 = 2.3 units
To make things a little quicker, use our unit calculator or check the table below:
Is 25ml one unit of alcohol?
Spirit measures and wine glass sizes – Pubs and bars used to commonly serve spirits (like vodka, gin, rum or whisky) in 25ml measures – that’s about one unit of alcohol per measure. But these days many pubs and bars have switched to 35ml or 50ml measures – meaning you might be having a lot more alcohol without realising.
If you drink at home, a good way to avoid accidentally pouring too much and limit how many units of alcohol you have is with a measuring cup. Get one from the Drinkaware shop today. There has been a trend towards larger servings for wine too. If you order a large glass of wine, that means you’re having 250ml – and that is likely to contain at least three units of alcohol in a single glass.
So, drinking three large glasses of wine is the same as drinking a whole bottle (750ml), which, like any binge drinking, can have serious consequences for your health. Binge drinking in the UK, as defined by the NHS, is drinking more than eight units of alcohol in a single session for men, and more than six units of alcohol in a single session for women.

What is 40 units of alcohol?
The ABV is widely available and shown on beer pumps, bottles, cans and so on. For example, most whisky has an ABV of 40%. A 1 litre (1,000ml) bottle of this whisky therefore contains 400ml of pure alcohol. This is 40 units (as 10ml of pure alcohol = one unit ).
How many units is 25 ml of vodka?
Vodka, like all spirits, is a strong alcoholic drink. A typical-strength single (25ml) measure of vodka will have 1 unit of alcohol in it. And if your drink has a double measure, that means double the amount of alcohol (and calories).

Having a high alcohol tolerance puts you at risk of alcohol dependence,
Is 10 units of alcohol too much?
Alcohol is a powerful chemical that can have a wide range of adverse effects on almost every part of your body, including your brain, bones and heart. The short-term effects of alcohol consumption are outlined below. This information is based on the assumption that you have a normal tolerance to alcohol.
Dependent drinkers with a higher tolerance to alcohol can often drink much more without experiencing any noticeable effects. After drinking 1 to 2 units of alcohol, your heart rate speeds up and your blood vessels expand, giving you the warm, sociable and talkative feeling associated with moderate drinking.
After drinking 4 to 6 units of alcohol, your brain and nervous system starts to be affected. It begins to affect the part of your brain associated with judgement and decision making, causing you to be more reckless and uninhibited. The alcohol also impairs the cells in your nervous system, making you feel light-headed and adversely affecting your reaction time and co-ordination.
- After drinking 8 to 9 units of alcohol, your reaction times will be much slower, your speech will begin to slur and your vision will begin to lose focus.
- Your liver, which filters alcohol out of your body, will be unable to remove all of the alcohol overnight, so it’s likely you’ll wake with a hangover.
After drinking 10 to 12 units of alcohol, your co-ordination will be highly impaired, placing you at serious risk of having an accident. The high level of alcohol has a depressant effect on both your mind and body, which makes you drowsy. This amount of alcohol will begin to reach toxic (poisonous) levels.
Your body attempts to quickly pass out the alcohol in your urine. This will leave you feeling badly dehydrated in the morning, which may cause a severe headache. The excess amount of alcohol in your system can also upset your digestion, leading to symptoms of nausea, vomiting, diarrhoea and indigestion.
If you drink more than 12 units of alcohol, you’re at considerable risk of developing alcohol poisoning, particularly if you’re drinking many units over a short period of time. It usually takes the liver about an hour to remove one unit of alcohol from the body.
- Alcohol poisoning occurs when excessive amounts of alcohol start to interfere with the body’s automatic functions, such as: Alcohol poisoning can cause a person to fall into a coma and could lead to their death.
- Drinking large amounts of alcohol for many years will take its toll on many of the body’s organs and may cause organ damage.
Organs known to be damaged by long-term alcohol misuse include the brain and nervous system, heart, liver and pancreas. Heavy drinking can also increase your blood pressure and blood cholesterol levels, both of which are major risk factors for heart attacks and strokes.
- Long-term alcohol misuse can weaken your immune system, making you more vulnerable to serious infections.
- It can also weaken your bones, placing you at greater risk of fracturing or breaking them.
- There are many long-term health risks associated with alcohol misuse.
- They include: As well as having a significant impact on your health, alcohol misuse can also have long-term social implications.
For example, it can lead to: Kindling is a problem that can occur following a number of episodes of withdrawal from alcohol. The severity of a person’s withdrawal symptoms may get worse each time they stop drinking, and can cause symptoms such as tremors, agitation and convulsions (seizures).
- Alcohol has a suppressing effect on the brain and central nervous system.
- Research has shown that when alcohol is removed from the body, it activates brain and nerve cells, resulting in excessive excitability (hyperexcitability).
- This can lead to behavioural symptoms such as seizures.
- With each alcohol withdrawal episode, the brain and nervous system becomes more sensitised and the resulting side effects become more pronounced.
This kindling effect can also occur after chemical stimulus to the brain or body, such as anti-convulsant medication. This means a person’s alcohol withdrawal programme needs to be carefully planned, with close monitoring of its effects.
Is 1 bottle of wine a week too much?

How many glasses of wine is 14 units?
Here’s just how many drinks equals the 14 unit weekly limit Four years ago, in 2016, the government updated the alcohol guidelines in the UK for the first time in more than two decades. The UK’s chief medical officer fully reviewed alcohol guidelines issued in 1995, and reduced the recommended maximum number of units to 14 for both men and women per week.
- At this limit people are keeping the health risks associated with drinking alcohol to a low level, says the CMO.
- If you do drink 14 units a week, you are advised to spread this over three days or more, rather than binge drinking them all at once.
- It says: “If you have one or two heavy drinking sessions, you increase your risk of death from long-term illnesses and from accidents and injuries.”
- It also advised that during drinking sessions you drink more slowly, drink with food and alternate your alcoholic drinks with a glass of water.
- The guidelines also warn pregnant women that they should aim to abstain from drinking entirely, when they were previously told they could safely drink one or two units a week at most.
- “Drinking alcohol in pregnancy can lead to long-term harm to the baby, with the more you drink the greater the risk,” it says.
The idea of counting alcohol units was first introduced in the UK in 1987 to help people keep track of their drinking, says the NHS. But how many drinks is 14 units equivalent to? Below, we outline exactly what it means in real terms. One unit of alcohol (10ml or 8g) is the equivalent to: A single measure of spirits (ABV 37.5%); half a pint of average-strength (4%) lager; two-thirds of a 125ml glass of average-strength (12%) wine; half a 175ml glass of average-strength (12%) wine; a third of a 250ml glass of average-strength (12%) wine.
- For low-alcohol wines (11% ABV), 14 units equals:
- Just over one and a half bottles; five 250ml glasses; around seven 175ml glasses; 10 125ml glasses.
- For high-alcohol wines (14% ABV), 14 units equals:
- One and a third bottles; four 250ml glasses; around six 175ml glasses; just under eight 125ml glasses.
- For low-alcohol lagers (3.8% ABV), 14 units equals:
- Just over eight 440ml cans; just over six pints; five and a half 660ml bottles.
- For high-alcohol lagers (5.2% ABV), 14 units equals:
- Six 440ml cans; around four and a half pints; just over four 660ml bottles.
- If you still aren’t sure the you can work out how many units there are in any drink by multiplying the total volume of a drink (in ml) by its ABV (measured as a percentage) and dividing the result by 1,000.
: Here’s just how many drinks equals the 14 unit weekly limit
Is 50 units of alcohol a lot?
How much alcohol is safe to drink? – For an adult who is otherwise well, the UK government recommends keeping to less than 14 units per week for men and women.

Is 100 units of alcohol a lot?
Defining Alcoholism Based on Symptoms – Doctors and other medical professionals rely on a list of signs and symptoms that indicate a person has developed alcoholism. Before we get to those signs and symptoms, there is a general rule relating to the volume of alcohol one consumes as an alcoholic.
- One unit of alcohol equals 10 ml of pure alcohol by volume.
- It can be calculated by multiplying the strength of a particular drink (aka ‘ABV’) by the quantity of the alcohol consumed, then divided by 1000.
- As a general rule, a pint of strong lager contains between two and six units of alcohol while the typical bottle of wine contains tens units.
A bottle of spirits is about 40 units on average. It is generally accepted that a man who consumes 100 units or more per week is alcohol dependent; a woman who drinks more than 70 per week is also dependent. However, you can be an alcohol abuser without being classified as alcohol dependent.
Men – 2 to 3 units of alcohol per day; no more than 21 units per week Women – 1 to 2 units of alcohol per day; no more than 14 units per week.
The government has since refined its guidelines to now say that both men and women should restrict their alcohol intake to no more than two units per day and 14 per week. This generally means one or two drinks per day, maximum. Anything more than that constitutes alcohol abuse which, if left ignored, could eventually become alcoholism.
- Bear in mind that there is quite a bit of variation when applying the raw numbers offered by the government.
- Individual body size, weight, metabolism and other factors all play a role in determining how much alcohol a person can tolerate.
- This is why doctors look at the signs and symptoms of alcoholism along with alcohol volume.
Those signs and symptoms are:
a need for alcohol to be part of all social gatherings routinely worrying about alcohol being available gradual social isolation; drinking alone gradual financial problems due to drinking increased defensiveness about drinking habits hiding alcohol at home and work increased frequency of drinking episodes increased binge drinking episodes increased consumption in order to continue feeling good.
We have explained the physical, mental and practical effects of alcoholism. Alcoholism is something that should not be taken lightly. If you exhibit any of the symptoms listed above, you may already be an alcoholic. At the very least, you are on the road to alcoholism.
