"Just to stir up Henry Ford's mob ." Which I take to mean our colonial cousins.
It will, no doubt, gratify you, Thornley, to know that here in Old Blighty your stirring is working well!!
Little ole GB's population is just over one fifth of "Henry Ford's" mob (in one thirty-ninth of the area!) and we
like our miles and we are doing our best to hang on to the tattered remnants of our once glorious confusing Imperial system despite all the efforts of that upstart johnny-come-lately lot called the European Union!
But incursion to our isle's esoteric system of measurements has happened.
However it has to confessed we are rather confused in our use of Napoleon's blasted artificial and un-anthropomorphic metric system.
For example when it is a hot day we talk of the temperature in Fahrenheit (
"phew, high 80's today") but when cold in Centigrade
(brr, minus 3 today).
Horse races are run here and in Europe over furlongs (one eighth of a mile) and horses are sold in guineas (21 shillings or in modern money 1 pound 5 pence)
Petrol/gas is sold in litres but we buy it in pounds sterling "I put £20 of petrol in the car today"
Builders use a mongrel mix of metric and imperial "Can I have 4.5 metres of 4 by 2", plywood sheets (here and Europe) are sold in Imperial disguised as metric 2440 x 4880 i.e. 4' x 8'
Pubs sell beer in pints (here 20fl oz) and you can still buy pints in some parts of France, Germany and Switzerland....
....and as to shoe sizes..... (an American shoe size unit is equal to one barleycorn!)
Now as to the
Camino Frances - I know it is 500 miles but 800 kilometres sounds a lot further doesn't it?
