Alcohol Units Calculator

Ever wondered how many units there are in a drink? Ever sat in a pub and argued about that very point? I have. Many people just do not know how many units they are in the drink they are having. Without this knowledge you are at a disadvantage when trying to decide when is enough.

A weak 3.6% pint of beer has 2 units in it. In the UK to remain within the drink drive limit you can have between 1-2 pints except that many pints are not 3.6%, many pints are 5.0%. So what difference does that make? Well a 5% beer has 2.84 units in it. Now the 1-2 pints is much closer to 1 than 2. This App can can be used to calculate the number of units in a drink

This App is not restricted in the amounts that can be entered unlike other similar Apps. You are not restricted by the values specified on picker wheels. You can enter ANY amounts using US fl Ozs, millilitres, centilitres, litres, UK pints.

Set the percentage alcohol, the volume and the number of drinks. The volume for the drink can be expressed in US fl Ozs, millilitres, centilitres, litres, UK pints using the switches above the drink amount.

As you enter value the calculated units change based on the current setting. Change all the values that need to be changed and the calculated units will tell you the amounts of units of alcohol there are in a drink.

Most alcohol percentages are ABV but, especially in the US, ABW is used. There is a significant difference in the resulting units so it is important to get this selection correct.
