In the UK we use a strange combination of Imperial and metric measurements.
A few examples:
all road signs etc are in miles / yards / miles per hour; beer and milk is sold in pints but fruit juice is sold in litres, when we buy our petrol (gas), it's priced in pence per litre, but we tend to express fuel efficiency in miles per gallon.
Food in supermarkets is sold by metric weight, but many supermarkets still list the price per pound for loose produce (as well as price per kilo).
Temperatures in the weather forecast are expressed in degrees Celcius, but many people will convert this mentally to fahrenheit.
