It can be confusing here in the UK:
We use Miles on road signs/directions,
Gallons and Litres for petrol, Pints for beer, but wine in in ml - but also a large or small glass!!
Yards/inches AND Meters/centimeters for material and length,
Kilograms and grams AND pounds and ounces for weighing/measuring and recipes - but use one or the other only!
Shopping = a mixture of everything!!
It is a mixed up world.
