How many beers a week is equivalent to 150ml of PURE alcohol?

Question

let's say a beer is 4.5% pure alcohol.

Answer 1

100ml of beer will then have 4.5ml of alcohol.  3300ml, or 3.3litres of beer will have 148.5ml of pure alcohol.  As there are 1.76pints in every litre, 5.8 pints have 148.5mls of pure alcohol, in real life you'd round it to 6 pints.

Answer 2

Your calculation seems right to me.  I did the math and ended up with 9.4 cans for 150ml of pure alcohol; which equalled 7.05 16 oz. pints.
