30 miles is 48.28 kilometres.
A mile is defined as exactly 1.609344 kilometres, so multiply the mileage by that factor: 30 × 1.609344 = 48.28 km. Rounding the factor to 1.61 is close enough for everyday distances. For a quick estimate, add about 60 percent — 30 plus 18 gives roughly 48 km, within a rounding error of the exact 48.28 km.
Thirty miles is 48.28 km, close enough to the 50 km ultramarathon distance to be confused with it — that distance is 31.07 miles, so a thirty-mile run falls about a mile short of the shortest standard ultra. Thirty miles is also roughly the practical daily range of an early electric vehicle and a common threshold in commuter tax and mileage-allowance rules, both of which are written in whole miles in the US and whole kilometres elsewhere.
