Calculating Alcohol Units: The Core Formula
Understanding how many units are in a drink like a Heineken is not complex once you know the core formula. An alcohol unit is a measure of pure alcohol content, and the calculation is based on the drink's volume and its Alcohol by Volume (ABV) percentage.
The formula is:
$(ABV \% \times Volume \text{ (ml)}) \div 1000 = Units$
For example, to calculate the units in a 330ml bottle of Heineken with an ABV of 5%, the equation is $(5 \times 330) \div 1000 = 1.65$ units. This simple calculation method can be applied to any alcoholic beverage, provided you have its ABV and total volume.
Heineken Original: Bottles, Cans, and Pints
Heineken's most popular offering, the classic green bottle and can, typically has a 5% ABV. However, the number of units changes depending on the size of the container.
330ml Bottle and Can
A standard 330ml bottle or can of Heineken Original contains 1.65 units of alcohol. This is calculated as $(5 \times 330) \div 1000 = 1.65$ units. This is a common size for multipacks and is widely available.
500ml Can
Larger 500ml cans of Heineken Original contain more units. With a 5% ABV, a 500ml can works out to 2.5 units of alcohol, calculated as $(5 \times 500) \div 1000 = 2.5$ units.
650ml Large Bottle
In some markets, you can find 650ml bottles. These contain a significantly higher number of units, with a 5% ABV translating to 3.25 units.
Pint of Draught Heineken
When enjoying a pint (568ml) of draught Heineken, the unit count is slightly different from the cans. For a 5% ABV beer, the calculation is $(5 \times 568) \div 1000 = 2.84$ units. This is an important distinction for those tracking their intake.
Understanding Different Heineken Variants
Heineken offers a range of products beyond the standard 5% lager, and each has a different unit count.
Heineken Silver
Heineken Silver is a lighter, lower-carb alternative with a 4% ABV. A standard 330ml bottle or can of Heineken Silver contains $(4 \times 330) \div 1000 = 1.32$ units. This is a good option for those seeking a beer with fewer units per serving.
Heineken 0.0
As the name suggests, Heineken 0.0 is a non-alcoholic beer with virtually 0% alcohol content. This means it contains 0 units of alcohol, making it an ideal choice for those wishing to avoid alcohol entirely while still enjoying the taste of beer.

Conclusion
While a definitive single answer to "how many units are in a Heineken?" doesn't exist due to varying product sizes and strengths, the information above allows you to easily calculate the unit count for specific Heineken beverages. From the 1.65 units in a standard 330ml bottle of Heineken Original to the 0 units in Heineken 0.0, understanding ABV and volume is key. Tracking your units is a crucial step for adhering to low-risk drinking guidelines, such as the UK's recommended maximum of 14 units per week, to maintain better health.
