The purpose of this calculator is to find how many units of alcohol exist in a given quantity of liquid when its AbV (% alcohol by volume) is known, and expressing this as units of drink (aka *standard drinks*) according to the country selected. There is a separate calculator to help in finding the AbV if it is given in some other form.
It is only a matter of keying in the AbV value, and the numerical value of the size of the quantity, adjusting the type of measure and country (where necessary) and clicking on [Calculate It].
There are other ways of using this calculator, but those can easily be found by experiment.
Clearly an AbV of over 100% cannot exist. An attempt to produce such a value will generate a warning message. To see this, try putting in a quantity of 1 cL and 10 units.
This calculator deals with 16 different countries having 11 different *standards*. An overview of this situation is given in the General Notes and there is also a calculator for Changing Values between countries.
The significant figures option should not be needed (the default value of 3 being adequate for all this work) but is there *just in case*.
Whatever the setting, unvalued zeros are not shown.
