Imperial gallon? Is MPG still in regular use in the U.K.?
Surprised to not see km/l. Is this a selectable display based on preference?
Welcome to the UK. We sell petrol in litres, but measure economy in miles per gallon (proper gallons - 8 pints). All road signs are in miles, but you'll also see temporary signs telling you that there are roadworks 800m ahead.
We love to mix metric and imperial - I bought some thermocure the other day to flush my MGB - the instructions say "Remove coolant and add one litre of Thermocure per two gallons of water"
Beer is still sold in pints, but you can buy milk in pints or litres.
