1MB is equal to 2^20 bytes. MB, the full name is "MByte", a storage unit in computers. Byte is a unit of measurement used by computer information technology to measure storage capacity. It is a string of binary digits processed as a unit and is a small unit that constitutes information.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

1MB is equal to 2^20 bytes.

1MB=1024KB= 2^20 B.

1. Byte (Byte) is a unit of measurement used by computer information technology to measure storage capacity. A string of binary digits processed as a unit is a small unit that constitutes information. The most commonly used byte is an octet, that is, it contains an eight-bit binary number.

2. KB kilobytes (Kbytes), a unit of computer storage capacity, also commonly expressed in KB. 1KB=1024 bytes.

Kilobyte (Kilobyte), often written as kB, KB or K, is a unit of information measurement that is commonly used today to indicate the storage capacity of storage media with general capacity such as memory.

This unit of measurement is easily confused with KiB. According to the IEC naming standard, the binary standard naming is KiB, MiB, etc. Linux and macOS X have adopted decimal standard naming. However, Windows still incorrectly labels KiB as KB.

3. MB, English abbreviation, a storage unit in computers, full name MByte.

MB (full name MByte): A storage unit in computers, pronounced as "mega".

The data units MB and Mb (note the capitalization of the B letter) are often mistaken for the same meaning. In fact, MByte means "megabyte" and Mbit means "megabit". MByte refers to the number of bytes, and Mbit refers to the number of bits.

Although the "Byte" in MByte is translated the same as the "bit" in Mbit, both are bits and are units of data measurement, but they are completely different. Byte is the "number of bytes" and bit is the "number of bits". In computers, every eight bits is one byte, that is, 1Byte=8bit, which is a 1:8 correspondence. Therefore, when writing units, be sure to pay attention to the capitalization and meaning of the letter B.

Extended information:

Gigabyte (GB, Gigabyte, also known as Jigabyte or Jinggabyte in China byte or gigabyte or halberd), often abbreviated as G.

GB is a decimal unit of information measurement. Gigabyte is often confused with Gibibyte, the binary unit of information measurement. It is often used to indicate the storage capacity of storage media with larger capacity such as hard drives and memories.

1GB (Gigabyte, gigabyte, billion bytes, also known as "gigabyte") = 1024MB = 2^30 B.
