perl · Answer

thats a bit weird that its an exact conversion factor

also 
1 inch = 2.54 cm (exactly)

mathstudent55 · Answer

1 in. = 2.54 cm (exact)
12 in. = 1 ft (exact)
5280 ft = 1 mi (exact)
100 cm = 1 m
1000 m = 1 km
Apply all the conversion factors correctly, and you get:
1 mi = 1.609344 km (exact)
Also, notice the period after in., but no period after ft or in; this is the correct convention.
