Difference Between MB and GB (With Table)

MB vs GB

Every digital product comprises storage capacity which is within the system and cannot be seen, this space allows the user to save their information in the system for further use, as they are saved until deleted.

Internet connections also have a system which allows the user to get track of how much data is used by them, for measuring this usage there are different units used, which are even standards at international level as well.

The rate of data transmission in telecommunications And Computer use is based On the Number of Bits, Characters Block in their number system. These are measured in multiple units of bit per second or byte per second.

The bit is an abbreviation for Binary digit which is the amount of stored information in a digital device. It is a variable that has two possible values denoted as Arabic numeral 1 (true) 0 (false). The binary systems have variation in definitions.

A byte is said to be a unit of digital information used in computing and telecommunications It consists of eight bits to encode a single character of text. It uses teletypewriter codes like the 6-bit codes of the US army and navy, which is now used across the world as well.

In an earlier time when the internet was new to the world the transmission cost as much, so to reduce transmission cost, the 8-bit code was developed and formed as the basis of early

Internet use. Today a byte consists of 16 bits, a kilobyte 1024 bytes, a megabyte is 1024 kilobyte, a gigabyte is 1024 megabytes.

There are different representations in a technical language like C language, for example, a byte is represented by at least 8 Bits while in C++ programming language; it is represented by 8,9,16,32, or 36 bits.

There are multiple units of bytes, prefixes such as kilo (K), mega (M), Giga (G), and

So on. Multiple units are expressed in powers of 2 and have different Definitions. Every unit follows the international system of units.

The difference between MB and GB is the difference in their number of bytes. Both of them are used for digital storage and transmission, but yet are different from each other.

What is MB?

MB is the abbreviation of a megabyte. Megabyte is used as the digital storage and for the transmission of information. Every device has its storage for example computers have different MB for storage and mobile phones have different MB for storage.

The mega is equivalent to 1000000 in the international system of units. Thus, one megabyte can be considered as one million bytes of information, which is a great space.

A unit of computer memory or the storage capacity equal to 1,048,576 bytes. One megabyte consists of 1024 kilobytes. Megabyte is often used to describe the size of large files, for example, JPEG image files or RAW images from digital cameras.

Megabyte is a smaller unit than a gigabyte and thus the average plan of 500 MB lasts for around 6 hours and t steam about 100 songs or to watch the 1-hour video in high quality. Price of plans depends on the companies.

MB is different from Mb. MB stands for megabyte whereas Mb stands for megabit, and one megabyte is equivalent to 8 megabits. Their units are different from each other.


What is GB?

GB is the abbreviation of gigabyte; it is multiple units of the byte is used for digital information storage and uses the unit Symbol GB. The SI uses the definition of one billion bytes in one gigabyte. It has also been Used to denote the gigabyte (1073741824 bytes).

One GB or gigabyte is 1,000,000,000 bytes, it is equivalent to 1,000 megabytes. Sometimes gigabyte is abbreviated as gigs as well.

GB is used to measure storage capacity as well, for example, a standard DVD has space up to 4.7 GB of data, likewise, SSD cards in mobile phones have capacity up to 256 GB and the hard drive has capacity up to 750 GB.

Storage in devices in terms of GB is measured up to 1,000 GB, above 1,000 GB the capacity is measured in terabytes. RAM (a form of memory) is also measured in GB. For example, in computer RAM there is space up to 16 GB or a tablet might require 1 GB of system space.

GB is of higher capacity than MB. One GB data plans are offered by different companies in which it can probably run up to 12 hours, 200 songs could be streamed, and 2 hours of high-quality video can be watched. Price of data plans varies as per the companies.


Main Differences Between MB and GB

  • MB is an abbreviation of megabyte whereas GB is the definition of a gigabyte.
  • 1000 kilobytes make 1 megabyte on contrary 1000 megabyte makes 1 gigabyte.
  • MB is used in measuring the size of files like images, whereas GB is used in measuring the capacity of storage in systems.
  • GB is the higher unit than MB, but above GB there is a terabyte.
  • 500 MB data plan allows up to 100 songs streaming and 1 hour of high-quality video whereas 1 GB data plans allow up to 200 songs streaming and 2 hours of high-quality video.



Megabyte (MB) and Gigabyte (GB) are measuring unit of storage and transmission of information, but they have different capacities. Both of them follows an international system of units but also use binary definition depending upon how they are used.

MB and GB use different bytes like MB uses 1048567 bytes in case of computers and GB uses 1073741824 bytes. Both of them have different definitions and uses in their spheres.
