I' justy been reading through some old Popular Mechanics magazines.
I was surprise to find a reference to different US and UK Inches (PM Feb '63 p58) "...the British gallon is slightly is slightly large than the US version but the inch is slightly smaller there than here."
I know the Inch as used here in the UK now is defined as 25.4mm, the same as the US inch but, has it ever been different?
