About MB to GB

MB to GB is the conversion from MB to GB.

To understand the “MB” and “GB” better, lets first introduce “byte” to you. According to Wikipedia, a byte is a unit of digital information that usually consists of 8 bits. In history, it was the number of bits used to encode a single character of text in computers. Therefore, the byte is the smallest addressable unit of memory storage in many computer architectures.

Tip: A bit is a basic unit of digital information and computing information. The name “bit” is derived from binary digit representing a logical state with one of two possible values (e.g. 0 or 1).

MB is a unit symbol of megabyte that is a multiple of the unit byte for digital information. The unit prefix “mega” is a multiplier of 1,000,000 (106) in the common decimal system. So, 1 megabyte is one million bytes. However, in binary digit, a mega is a multiplier of 1048576 (220). That is, one megabyte is equal to 1048576 bytes of binary digit info.

Tip: MB can also refer to megabit (Mbit) which is equal to 1,000,000 (106) bit in the decimal system. While in the binary system, there is mebibit; the 1 megabit = 1048576 (220) bit.

GB, similarly, is a unifying symbol of gigabyte which is a multiple of 1,000,000,000 (109) unit bytes for digital information in the decimal system. In the binary system, one gigabyte is 1073741824 (230) bytes.

Tip: Similarly, GB sometimes also refers to gigabit (Gbit) which is one billion bits in a decimal system and there is gibibit equaling to 1073741824 (230) bits in a binary system.

Other related digital information units:

KBkilobyte or kilobit. 1 kilobyte equals to 1,000 (103) bytes in the decimal system or 1024 (210) bytes in the binary system. 1 kilobit is 1,000 bits in the decimal system while in the binary system, there is kibibit that is equal to 1024 (210) bits.

TBTerabyte or Terabit. One terabyte equals to 1,000,000,000,000 (1012) bytes in the decimal system or 1099511627776 (240) bytes in the binary system. 1 terabit is 1,000,000,000,000 (1012) bits in the decimal system while in the binary system, there is tebibit which is equal to 1099511627776 (240) bits.

Bytes to MB (Megabyte)

From the above definition of MB, you can know that 1MB is 1,000,000 (106) bytes in the decimal system while 1048576 (220) bytes in the binary system. In 1998, the International Electrotechnical Commission (IEC) proposed standards of binary prefixes requiring the use of megabyte to strictly denote 10002 (106) bytes and mebibyte to denote 10242 (220) bytes. This proposal was adopted by the IEEE, EU, ISO and NIST by the end of 2009. Yet, the megabyte is still been widely used for decimal and binary systems.

Decimal Base

1 MB = 1,000,000 bytes (= 10002 bytes = 106 B)

This definition is used in networking contexts and most storage media such as hard drives, flash-based storage and DVDs. It is also used in computing like CPU clock speeds & measures of performance.

Binary Base

1 MB = 1,048,576 bytes (=10242 B = 220 B)

This definition is used by Microsoft Windows for computer memory (e.g. RAM).

Mixed Base

1 MB = 1,024,000 bytes (=1000×1024 B)

This definition is usually used to describe the formatted capacity of the 1.44 MB 3.5-inch HD floppy disk, which actually has a capacity of 1,474,560 bytes.

Bytes to GB (Gigabyte)

Similarly, the base of the gigabyte can be binary and decimal.

Decimal base

1 GB = 1,000,000,000 bytes (=10003 B = 109 B)

Binary base

1 GB = 1,073,741,824 bytes (=10243 B =230 B)

Conversions Between Bytes and Other Units

Bytes to KB: 1 KB = 1000 bytes (103 B) OR 1 KB = 1024 bytes (210 B)

Bytes to TB: 1 TB = 1,000,000,000,000 bytes (1012 B) OR 1 TB = 1024 bytes (240 B)

How Many MBs in a GB (MB to GB)

As for how many MB are in a GB, how many MB in 1 GB, how many MB in GB or how much MB in a GB, you can convert GB to MB based on the above base.

Convert KB to MB

1 MB = 1000 KB (Decimal)

1 MB = 1024 KB (Binary)

So, as for KB vs MB, there are many questions. The following list the common ones:

Q1: Which one is bigger KB or MB? / What’s bigger MB or KB? / Is KB or MB bigger?

A1: MB is bigger.

Q2: Is KB bigger than MB?

A2: No, MB is bigger than KB.

Q3: Which is larger KB or MB?

A3: MB is larger.

Q4: Is KB smaller than MB?

A4: Yes, it is.

Tip: MB and KB are usually used to describe the speed of data transfer. Kb/s, also known as kbit/s, refers to kilobit per second (kbps). Mb/s, also called Mbit/s, means megabit per second (Mbps). So, kb/s to MB/s is 0.001 (10-3). That is, 1 Mb/s equals to 1000 kb/s.
