千米是公制中的长度单位，相当于 1000 米。
英里也是长度单位，等于 1760 码。
例：
Input:5.5 Output:3.418 Input:6.5 Output:4.039
公式：
1 kilometer equals 0.62137 miles. Miles = kilometer * 0.62137 Kilometer = Miles / 0.62137
# Python3 program to convert
# kilometers to miles
# driver code
kilometers = 5.5
# conversion factor
conv = 0.621371
# calculate miles
miles = kilometers * conv
print('%0.3f kilometers is equal to %0.3f miles' %(kilometers,miles))
kilometers = 6.5
# calculate miles
miles = kilometers * conv
print('%0.3f kilometers is equal to %0.3f miles' %(kilometers,miles))输出：
5.500 kilometers is equal to 3.418 miles 6.500 kilometers is equal to 4.039 miles
