Mile

A mile was a unit of distance measurement commonly in use in the United Kingdom, particularly during the Third Doctor's exile on Earth. The Doctor's time sensor was calibrated to read in terms of Venusian miles, and he once reckoned that there were about .225 Venusian miles for every Earth mile. (TV: The Time Monster)

4000 metres was equivalent to nearly 3 miles. (AUDIO: The Screaming Ceiling)

The mountains on Judoonia were 1,000 miles high. (AUDIO: Judoon in Chains)

A Venusian mile was approximately 4.5 Earth miles. (PROSE: The Rise and Fall of Señor 105)
