How many mm are in a mile? (1 in= 2.54cm)?

1 mile = 5280 feet = 63360 inches
1 inch = 2.54 cm = 25.4 mm

63360 inches * 25.4 mm
= 1609344 mm

It might be wrong, because you have to do a proportion: (1mm)/(1M mil) = (x mm)/(44350 mi) You will in fact get about 1/20th of a mm and that is pretty darn hard to draw!

1 mile = 1600metres

1 metre = 1000mm

1600*1000

1,600,000

5280 x 12 x 25.4 = 1609344
