What are Kibibytes (KiB), Mebibytes (MiB), and Gibibytes (GiB)?

They are a distinct set of storage items used to precise/measure file sizes. On the floor, Kibibytes, Mebibytes, and Gibibytes might sound just like Kilobytes Gigabytes, Terabytes, Petabytes and Exabytes – and usually used interchangeably – however they are not the identical.

The items of measurement for kilobytes, megabytes, gigabytes, and many others. are all hundreds of occasions bigger than each other. This is the file storage decimal measurement system. On the opposite hand, the binary measuring system makes use of kibibytes, mebibytes, gibibytes, and many others.; A mebibyte is the same as 1024 kibibytes, a gibibyte to 1024 mebibytes, and so on. The International Electrotechnical Commission (IEC) established the mebi prefix in December 1998, along with its companion binary prefixes (kibi, gibi, tebi, pebi, exbi, zebi, and yobi). Prior to then, multipliers within the binary and decimal methods have been each referred to by the International System of Units (SI) metric prefixes.


Kilobytes, megabytes, and many others., have been used interchangeably each for measurements till the binary system’s items acquired names. Differences started to emerge as computing know-how superior. The decimal technique was primarily utilized by disk drive producers to mark the sizes of their onerous disk drives (HDD) and solid-state drives (SSDs). Operating methods, alternatively, incessantly used the binary system to gauge storage capability. This explains why a pc’s working system would point out a tough drive with a capability of 100 MB as having solely 95.37 MB.

These types of discrepancies led the IEC to create a set of prefixes that have been supposed for use solely when referring to binary measurements. Binary items getting used are as a result of they’re a extra correct unit of measurement. Computers work in binary, so a binary measurement system will at all times present a greater illustration of file sizes.

What is Kibibyte?

Kibibyte is a binary unit for measuring reminiscence measurement which is equal to 1024 bytes. Given that bis a is a binary amount, this unit has been proposed by those that oppose utilizing SI items. Hence, it’s easy for anybody that doesn’t wish to measure their machine reminiscence measurement with Kilo, a decimal reminiscence unit.

A “kibibyte” is the same as 1024 bytes whereas a kilobyte naturally interprets to 1000 bytes. A kilobyte has usually been used to discuss with each 1000 bytes and 1024 bytes however this was earlier than the IEC got here up with completely different storage items. Most storage producers measure and label capability in base 10. This implies that 1 kilobyte = 1000 bytes; 1 megabyte = 1000 kilobytes; 1 gigabyte = 1000 megabytes, 1 terabyte = 1000 gigabytes, and so on.

Decimal items are at all times smaller compared with the binary unit. Take for instance; a kibibyte is greater than a kilobyte as a result of there are solely 1000 kilobytes to 1024 in a kibibyte. It would possibly simply be a small distinction when speaking a few single kilobyte however as the dimensions will increase, the distinction may even enhance.

What is Mebibyte?

The phrases mebibyte and megabyte are carefully associated and usually used as synonyms, although technically they don’t discuss with the identical quantity of capability. A mebibyte is the same as 1,048,576 bytes whereas a megabyte is the same as 1,000,000 bytes. One mebibyte equals 1.048576 megabytes. There is a small distinction between these two and one of many explanation why it’s usually used synonymously.

Differences between Megabyte and Mebibyte

  • Megabyte is a a number of of 1000 whereas Mebibyte is a a number of of 1024
  • The unit image for the megabyte is MB whereas the unit image for the mebibyte is MiB
  • A megabyte is estimated as 1,000,000 bytes whereas the Mebibyte is strictly 1,048,576 bytes.
  • Sometime1 MB refers to each 1000 Kb or 1024 Kb whereas 1 MiB is at all times 1024 Kb
  • Disk producers largely use decimal prefixes or MB whereas Memory producers generally use a binary prefix or MiB.
  • Storage gadgets reminiscent of HDDs and Flash drives nonetheless use MB for calculating storage measurement and alternatively, most working methods like Windows use mebibytes to report file and storage sizes.

What is Gibibyte?

A gibibyte (GiB) can be a unit of measure of capability utilized in computing. A gibibyte is the same as 1,073,741,824 bytes whereas a gigabyte is the same as 1,000,000,000 bytes. This implies that one gibibyte equals 1.074 gigabytes and alternatively, one gigabyte equals 0.93 gibibytes That’s a distinction of about 7%. As talked about earlier, because the storage will increase, the distinction between the 2 methods turns into magnified.

Imagine you get a 1 TB onerous drive, it gained’t have 1,000 gigabytes (GBs) of storage. Instead, it’ll have round 931 GBs of storage. This distinction may result in discrepancies when viewing the identical file on completely different working methods. It additionally applies when you’re sharing recordsdata. If you obtain a file from a Mac to your Windows you’ll discover a drop within the weight of the file.


Kibibytes (KiB), Mebibytes (MiB), and Gibibytes (GiB) are the binary system of calculating storage versus Kilobyte (KB), Megabyte (MB), Gigabyte (GB) which is the decimal system of calculating storage. The former was created in December 1998 by the International Electrotechnical Commission (IEC) as a result of binary items are extra correct items of measurement on account of Computers additionally working in binary. It was to create a distinction as a result of Kilobytes, Megabytes may imply two various things. But now, there may be extra readability. A kilobyte (KB) is 1000 bytes and a Kibibyte is 1024 bytes and this additionally applies to larger storage items.

What is the most important unit of reminiscence?

The largest unit of reminiscence measurement that we use is the terabyte (TB). This unit is about equal to a trillion bytes. However, there may be additionally the Petabyte, which is 1 quadrillion bytes, however it isn’t incessantly used.
