3 miles is 4.83 kilometres.
A mile is defined as exactly 1.609344 kilometres, so multiply the mileage by that factor: 3 × 1.609344 = 4.828 km. Rounding the factor to 1.61 is close enough for everyday distances. For a quick estimate, add about 60 percent — 3 plus 1.8 gives roughly 4.8 km, within a rounding error of the exact 4.83 km.
Three miles is 4.83 km — just under the 5K race distance, which is why American runners often treat 'three miles' and 'a 5K' as the same session despite the 5K being about 180 metres longer. Three miles is also roughly the distance most people will walk rather than drive, and the radius planners use when they talk about a neighbourhood being walkable. At an ordinary walking pace of three miles an hour it is, conveniently, an hour on foot.
