Hi All

Why is beer sold in 440 ml cans?

500ml - half a litre I can understand, 568 ml - a pint I can understand,
but 440 ml doesn't convert to anything!

You will think that I am slightly sad for having noticed
this, but on pondering the 13.5% extra free offer on some
beer cans, I realised that:
440ml + 13.6% = 500ml (0.5 litre)
500ml + 13.6% = 568ml (1 pint)

I can't believe this is a coincidence.
