A standard drink is a way to measure how much alcohol you're consuming. It's typically defined as 10 grams of pure alcohol, though in the US, it's defined as 14 grams. The concept of standard drinks was introduced to help people keep track of their drinking and lower health risks. The number of standard drinks in a beverage depends on its size and alcohol strength. For example, a pint of mid-strength beer is approximately 1.5 standard drinks in Australia, while a pint of full-strength beer is approximately 2.1 standard drinks. In the US, a 12-ounce beer, which is typically the size of a domestic beer can or bottle, is considered a standard drink.

What You'll Learn
A standard drink is 10g of alcohol
The amount of alcohol in a drink is measured in units, which are used to keep track of alcohol consumption and its relative health risks. Units are a way of expressing the quantity of pure alcohol in a drink. The number of units in a drink is based on the size of the drink and its alcohol strength.
A standard drink is always equal to 10g of pure alcohol. This definition has been adopted by more countries than any other amount. However, there is no international consensus on how much pure alcohol is contained in a standard drink, with values ranging from 8 to 20 grams. For example, in the United States, one standard drink contains roughly 14 grams of pure alcohol.
In the UK, a unit of alcohol equals 10ml or 8g of pure alcohol, which is the amount an average adult can process in an hour. This means that within an hour, there should be little to no alcohol left in the blood of an adult. However, this will vary from person to person.
To calculate the number of units in a drink, you can multiply the volume of the drink (in millilitres) by its percentage ABV and divide the result by 1,000. For example, a pint of strong lager (568ml) with an ABV of 5.2% contains 2.95 units of alcohol.
It's important to note that the definition of a standard drink varies from country to country, and the number of units of alcohol in a beverage can be read directly from the label in some countries.

A pint of mid-strength beer = 1.5 standard drinks
A standard drink is a way to measure how much alcohol you're consuming. It's important to understand standard drinks to keep track of your drinking and drink as safely as possible. The size of the container is not the best way to measure a drink, as some "single-serving" drinks may be equivalent to two or more standard drinks.
In Australia, a standard drink contains 10g of pure alcohol. This is the same in the UK, where one unit or standard drink equals 8g or 10ml of pure alcohol. In the US, a standard drink is slightly higher, at 14g of pure alcohol. This is about half an ounce, which is slightly more than the typical person can metabolize in an hour.
When it comes to beer, the number of standard drinks will depend on the size of the beer and its alcohol content. A pint of mid-strength beer, which is typically around 3.5% alcohol, is approximately 1.5 standard drinks in Australia. This is because a 425ml glass of mid-strength beer, known as a schooner, is approximately 1.2 standard drinks, and a pint is larger at 568ml. Therefore, a pint of mid-strength beer is equivalent to about 1.5 standard drinks.
It's important to note that the number of standard drinks in a pint of beer can vary slightly depending on the specific alcohol content and serving size. Additionally, the way the alcohol is served can also impact the number of standard drinks. For example, a 375ml bottle of full-strength beer is usually 1.4 standard drinks in Australia, while a 285ml glass of full-strength beer, known as a pot or middy, is approximately one standard drink.

A pint of full-strength beer = 2.1 standard drinks
A standard drink is a way to measure how much alcohol you're consuming. It's a useful way to keep track of your drinking and to drink as safely as possible. A standard drink always contains the same amount of pure alcohol, which is typically 10 grams or 10 millilitres. This is the amount of alcohol that the average adult can process in about an hour.
In Australia, a standard drink is defined as containing 10 grams of pure alcohol. Beer bottles and cans sold in Australia are required by law to display the number of standard drinks they contain. A 375ml bottle of full-strength beer, for example, usually contains 1.4 standard drinks. A 285ml glass of full-strength beer is approximately one standard drink.
A pint of beer, however, is a different volume depending on where you are in the world. In the US, a pint is 473ml, whereas in the UK, a pint is 568ml. So, a pint of full-strength beer will contain a different number of standard drinks in each of these countries.
In the US, a 12-ounce (355ml) can or bottle of 5% alcohol domestic beer is considered a standard drink. Therefore, a US pint of full-strength beer (473ml) would contain approximately 1.3 standard drinks.
In the UK, a pint of beer is 568ml. Using the formula strength (ABV) x volume (ml) ÷ 1,000 = units, we can calculate that a pint of strong lager (ABV 5.2%) contains 2.95 units. This equates to approximately 2.1 standard drinks.

A pint of strong lager = 3 units of alcohol
The number of units of alcohol in a drink is based on two factors: the size of the drink and its alcohol strength. A unit is a simple way of expressing the quantity of pure alcohol in a drink. One unit equals 10ml or 8g of pure alcohol, which is roughly the amount of alcohol the average adult can process in an hour.
A pint of strong lager contains 3 units of alcohol. This is because lager generally has an ABV (alcohol by volume) of 5% or higher. This means that 5% of the volume of the drink is pure alcohol. To calculate the number of units in a pint of strong lager, you can use the formula: strength (ABV) x volume (in ml) ÷ 1,000 = units. For example, a pint (568ml) of strong lager (ABV 5.2%) would contain approximately 2.95 units of alcohol.
It's important to note that the ABV of lager can vary, and some stronger 'craft' beers can have an ABV as high as 12%. The higher the ABV, the more alcohol is present in the drink. Checking the ABV on the label of your drink or by asking bar staff is essential to understanding how much alcohol you are consuming.
Drinking guidelines recommend that men and women should not regularly drink more than 14 units of alcohol per week to keep health risks at a low level. This is equivalent to 6 pints of average-strength beer or 10 small glasses of lower-strength wine. Spreading your drinking over several days and incorporating drink-free days into your week can help you stay within these guidelines.

A pint of lower-strength lager = just over 2 units
A standard drink is a way to measure how much alcohol you're consuming. It's a useful way to keep track and ensure you don't exceed the recommended limits. In the UK, the idea of counting alcohol units was introduced in 1987 to help people monitor their drinking.
In the UK, one unit equals 10ml or 8g of pure alcohol, which is roughly the amount an adult can process in an hour. In Australia and the US, a standard drink is defined as containing 10g of pure alcohol.
When it comes to beer, the number of standard drinks or units depends on the size of the drink and its alcohol strength. A pint of strong lager, for example, contains around 3 units of alcohol, while a pint of lower-strength lager has just over 2 units.
So, if you're drinking a pint of lower-strength lager, you're consuming just over 2 units of alcohol. This is based on the assumption that the lager has an alcohol strength of 3.6% ABV (alcohol by volume). ABV measures the amount of pure alcohol as a percentage of the total volume of liquid in a drink. You can usually find the ABV on the labels of cans and bottles or by asking bar staff.
It's important to note that the definition of a "standard drink" or "unit" may vary slightly between different countries or regions. Additionally, the serving sizes and alcohol content of beers can vary, so it's always a good idea to check the specific details of the drink you're consuming.
