About this tool

Enter a distance and choose the direction. One mile is 1.609344 kilometres, so multiply miles by 1.609 to get kilometres and divide kilometres by 1.609 to get miles. Common running distances in miles are shown for reference.

The formula

Miles = kilometres ÷ 1.609344. Kilometres = miles × 1.609344. A quick mental trick is to multiply kilometres by 0.6, so 100 km is about 60 miles. The exact figure is 62.14 miles.

Common distances

5K is 3.11 miles, 10K is 6.21, a half marathon is 13.11 and a marathon is 26.22 miles.

Speed limits

UK road signs use miles per hour. A 30 mph limit is about 48 km/h, and 70 mph is about 113 km/h.
