Example How Many Kilobytes in a Megabyte

Computers & Internet / How Many Kilobytes in a Megabyte

- 1 kilobyte equals to 1000 bytes
- 1 megabyte equals to 1 000 000 bytes

So, the answer to the question, “How many kilobytes are there in a Megabyte?” seems to be obvious:

- 1 megabyte equals to 1000 kilobytes.

But don’t jump to conclusions. For example, manufacturers of computer memory use another system. It states:

- 1 megabyte equals to 1024 kilobytes.

The IEC Definitions

In 1998, the IEC (International Electrotechnical Commission)

The following table presents all the IEC definitions.

These new definitions could have solved many problems, but they are not commonly used yet, and most manufacturers, dealers and computer users ignore it. No wonder, most people do not even know what these terms mean.

- The bit (contraction from the phrase “binary digit”) is the fundamental unit of computer information. In means the amount of data that has one of the two possible values: digits 0 or 1.
- The byte (abbr. B) is the basic unit of computer information, consisting of eight bits. Bytes make up kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), petabytes (PB), exabytes (EB), zettabytes (ZB), and yottabytes (YB). The standard definition states that one kilobyte has 1000 bytes and so on, but according to the non-official meaning, one kilobyte has 1024 bytes.
- The International Electrotechnical Commission (IEC) – is the non-profit organization, developing International Standards for various spheres of electrotechnology. It has approved such terms, as Kibibit (Kibit), Kibibyte (KiB), Mebibyte (MiB), Gibibyte (GiB), Tebibyte (TiB), Pebibyte (PiB), Exbibyte (EiB).
