Whenever I ordered a 'pint' in England, I was always served in a glass that actually contained a true pint only if the glass was filled to the brim of the glass. As beer is invariably served with a head, I took to calculating the amount of beer that I actually received in my 'pint' glass. My calculations went like this: The glass is close to 75 millimetres internal diameter at the top (three thumb widths). The froth depth is about 15 millimetres (using my little finger nail that is 10 millimetres). Calculated volume of froth = 66.3 millilitres (say 66 millilitres). Volume of beer received as a 'pint' = 568 mL (from label on glass) - 66 mL = 502 mL (say 500 millilitres given the accuracy of the measurements).
