Know your units...

Do you know how many units your usual pint contains or how many are in a high ABV% glass of wine?  How often do you drink more the recommended daily units?  Do you think you could accurately estimate how many units you drink in a week or would you be surprised by the real figure?...

Whilst different drinks vary in size and strength, below is a rough guide to how may units of alcohol are in what you are drinking:

Beer, Lager and Cider:

4% - 330ml Bottle = 1.3 units,  440ml Can = 1.8 units, 568ml Pint = 2.3 units

5% - 330ml Bottle = 1.7 units,  440ml Can = 2.2 units, 568ml Pint = 2.8 units

6% - 330ml Bottle - 2.0 uniits, 440ml Can = 2.6 units, 568ml Pint = 3.4 units

9% - 330ml Bottle - 3.0 units,  440ml Can = 4.0 units, 568ml Pint = 5.1 units

Spirits (40%):

25ml Small Measure - 1.0 units, 35ml Large Measure - 1.4 units (multiply by two for double measures)

Wine (red, wine, rose or sparkling):

10% - 125ml Small Glass = 1.25 units, 175ml Standard Glass = 1.75 units, 250ml Large Glass = 2.5 units

           Bottle = 8.3 units

12% - 125ml Small Glass = 1.5 units,   175ml Standard Glass = 2.1 units,   250ml Large Glass = 3.0 units

           Bottle = 9 units
