It's a result of converting the number to decimal.
17.6513671875 does not mean 17 Kb and 651.36... bytes, it means 17 Kb
and 65136/100000 of a Kb. However, as a Kb is 1024 bytes rather than
1000 bytes, a fraction Kb in base 10 will often look odd. If you
multiply the value by 1024, you get the byte count, which is a whole
number:
17.6513671875 * 1024 = 18075
