15 miles is 24.14 kilometres.
A mile is defined as exactly 1.609344 kilometres, so multiply the mileage by that factor: 15 × 1.609344 = 24.14 km. Rounding the factor to 1.61 is close enough for everyday distances. For a quick estimate, add about 60 percent — 15 plus 9 gives roughly 24 km, within a rounding error of the exact 24.14 km.
Fifteen miles is 24.14 km. This is the range at which cycling becomes clearly faster than walking and clearly cheaper than driving, which is why it shows up so often in commuting studies as the practical upper bound for a bike commute. On a road bike at a steady fifteen miles an hour it is an hour's ride — the pace and the distance sharing a number, which is a coincidence of the imperial units and does not survive conversion.
