For the record, in the UK, and indeed most metric / english-speaking countries, it'll be metres (and kilometres).
A metre is the ISO unit for distance.
A meter is a device to measure things (not just distances).
Speeds are measured in miles per hour. This can be seen when driving a car, and also on road signage.
It's basically a mix. Yards are not really used outside really by people, but you will find feet and inches being used (alongside metres and centimetres) often in commercial settings.
Other examples of finding both things in the wild in use by people and companies in the UK: pints and litres. pounds and kilograms
Some units are imperial
People's height in Feet
People's weight in Stones+Pounds
Beer in Pints (proper pints, not american tiny-pints)
Roads in Miles
Temperature in C
Milk in Litres
Petrol in litres, but we also use miles/gallon
Food in grams from shops, but oz when buying steak at a pub
Bottles and Cans in ml
