Understanding Byte Sizes: The Difference Between Kilobytes and Kilobits

Anybody who knows anything about computers knows that a byte is 8 bits, a kilobyte is 210 bytes, a megabyte is 220 bytes, a gigabyte is 230 bytes, a terabyte is 240 bytes, and so on. You will rarely, if ever, find a person who uses the term kilobyte to mean 1000 bytes, except for hard drive manufacturers. Even then, they know they are technically incorrect but do it to exaggerate the capacity and possibly take advantage of potential consumers.

Background

The terms Kilobyte (KB) and Megabyte (MB) traditionally refer to:

1 KB 1000 bytes in the decimal system 1 MB 1000000 bytes in the decimal system

However, in the field of computing, especially when discussing memory and file sizes, these terms are often used to refer to binary values:

1 KB 1024 bytes, which is 210 1 MB 1024 KB, which is 1048576 bytes, or 220

The Need for Clarity

This overlap and ambiguity in terminology have caused significant confusion, especially as storage capacities have grown. Different operating systems and manufacturers sometimes use these terms differently, leading to discrepancies in reported sizes.

To resolve this issue, the International Electrotechnical Commission (IEC) introduced binary prefixes in 1998:

Kibibyte (KiB) 1024 bytes (210) Mebibyte (MiB) 1024 KiB, or 1048576 bytes (220) Gibibyte (GiB) 1024 MiB, or 1073741824 bytes (230)

Introduction of Binary Prefixes

The introduction of these binary prefixes helps to distinguish between the decimal and binary definitions, preventing miscommunication and ensuring greater accuracy in data storage and memory specifications.

Conclusion

Clarifying byte size terminology is crucial for both technical professionals and consumers. By using the appropriate terms, we can avoid confusion, ensure accurate measurements, and improve overall communication around computer data.
