Step 1

Choose your drink type and serving size.

The calculator will suggest a typical serving size, but you can edit the volume in milliliters (ml) and the alcohol strength in ABV%, to match your actual drink.

Step 2

Add more drinks and select “calculate” for the total standard drinks.

You can select the + sign to add up to five different drink types or volume. Select “calculate,” and the result showing the total number of standard drinks will be displayed below.

How does the standard drinks calculator work?

Think of the standard drinks calculator as a ‘converter’ that lets you compare apples with apples!

In Singapore, a “standard drink” is defined as containing 10 grams of pure alcohol (ethanol).
Because alcoholic drinks come in different strengths and sizes, converting alcoholic drinks into “standard drinks” helps you compare them.

You can calculate the number of standard drinks by multiplying the volume of the beverage (measured in milliliters) by the percentage of alcohol a drink contains, its ABV (or Alcohol by Volume), and then dividing the result by 12.7.
Why 12.7? Because 10 grams is roughly the weight of 12.7 ml of pure alcohol!

For instance, if you wanted to calculate the number of standard drinks in one measure (30 ml) of spirits at an ABV of 40%, this is what you would do:

Fret not! You can put your calculator away; SARD’s standard drinks calculator will do the math for you. Find out more about alcohol, standard drinks and responsible drinking here.
