I haven't found any later numerical definitions. There are some later acts so the gallon (or any submultiple other than the pint) can't be used in trade. My interpretation is that the pint is now 1/8 of 4.546 09 L, and is no longer tied to a weight of water (10 lb for the gallon, 1.25 lb for the pint). Those water weights are still approximately true, but no longer the definition. The pint is metricated.

This definition might well have been updated – I did not have quick access to a more recent Act.

But can the 1824 pint be now legally realised without reference to the metric system?

The definition of the pint is the definition found in EU directive 80/181/EEC – which restates the definition that has been in use in the UK since 1824. ________________________________ From:[email protected] [mailto:[email protected]] On Behalf Of Pat Naughtin Sent: 28 May 2011 04:20 To: U.S. Metric Association Cc: UKMA Metric Association; USMA Metric Association Subject: [USMA:50515] Re: Coffee mug On 2011/05/26, at 07:03 , Beranger wrote: If it says "CE PINT", it's a pint glass. Get over it!!!!! This is no doubt true, but isn't the pint in the UK defined in terms of the metric system as agreed in 1959 by the English speaking nations? See http://www.legislation.gov.uk/uksi/1995/1804/schedule/made where they consistently use the 1959 definitions. Doesn't this mean that the pint in the UK -- wherever used including pubs and milk delivered in glass bottles -- is a metric pint? I don't know what the letters CE mean but I think that I am safe in assuming that the word pint, in this context refers to a metric pint as agreed by the English speaking nations in 1859. By the way, in my measurements of pub pints in England , all ten of the pints I measured contained 500 millilitres or slightly less based on my methods and my assumption that the word pint means 570 mL. I did not allow for the liquid component of the froth content at all -- thank you for your advice on this -- I will consider it further.
