Please be aware of the difference between Kilobyte and Kibibyte. 1 Kilobyte = 1000 byte whereas 1 Kibibyte = 1024 byte.
Kilobytes are often used to promote commercial products while Kibibytes are used in computer science, development, etc.
The differentiation of both scales is quite new and still not commonly known.
