Despite using miles on road signs, the UK uses kilometres for many purposes — running events (5K, 10K), cycling distances in sport, and European distances. GPS navigation apps may default to km depending on settings. Paris is 344 km = 213.7 miles from London by road.
The UK is unusual in retaining miles for road distances while using metric for most other purposes. UK road signs show miles and yards (not metres). Speed limits are in mph. Rail distances are measured in miles. Scotland's Ben Nevis is 1,345 m = 4,413 ft high.
