If you want to know just how many units of alcohol you are taking into your body, do an audit. You may be surprised to find out how many you consume.

Working out the units in pub measures is easy, but at home? Gather together your glasses used for various drinks and establish their sizes. This is best done using a kitchen measure and water. Fill your glass with water up to the normal drinking level, then pour the water into a measuring jug. What size glass are you drinking? To work out how many units are in a glass try:

Amount of liquid (in Litres) x percent a.b.v.

i.e.        one standard measure spirit
0.025 Litres x 40% = 1 unit

A large (250mL) glass of 12% wine is:
0.25 Litres x 12% = 3 units

A wine glass at my home is:
0.19 Litres x 12% = 2.3 units
