To convert between Mile (mi) and Kilometer (km), use the following formulas:
1 Mile (mi) = 1.609344 Kilometer (km)
1 Kilometer (km) = 0.621371192237334 Mile (mi)
0.5 mi = 0.5 * 1.609344 km = 0.804672 km
3 mi = 3 * 1.609344 km = 4.828032 km
10 mi = 10 * 1.609344 km = 16.09344 km
26.2 mi = 26.2 * 1.609344 km = 42.1648128 km
100 mi = 100 * 1.609344 km = 160.9344 km
