1.609344 km = 1609.344 m = 1760 * 0.9144 m = 1760 yards = 1 mile by definition through the definition of the yard as 0.9144 m
Just checked, using 1cm=0.3937" is wrong in the wrong direction and makes it 0.999998 mile.

The yard is exactly 0.9144 m, but I always thought it was the inch that was official: 1 inch = 2.54 cm. The reciprocal of that is 0.3937007874015748031496062992126 according to usoft calculator so maybe the conversion factor is set up as 0.393701
