Have you ever wondered what the numbers on a pint glass mean? The man size t-shirt comes with 562 on it, which is close to 568 the volume of a pint in millilitres. However, it’s not close enough and anyway a pint is a pint. To give its volume in millilitres is to treat it as derivative and secondary. In any case, the half pint shirts have 402 on them which is not half of 562 even if they were in millilitres.
It turns out that the numbers denote the UK weights and measures office that tested the volume of the glass. This document lists the various UK authorities and their numbers. 562 is the number associated with Bury. And 402 is associated with Leistershire.
