Data Units Conversion

Welcome to our online extended data storage unit conversion calculator. It is the best place where you can make conversions between a great number of various data units like byte, kilobyte, megabyte, terabyte, petabyte, and many others, as well as make a number of conversions between data transfer rate units. We both calculate decimal and binary multiples of bytes, and our data storage unit converter is very easy to use. To start your specific conversion operation, please, select a unit below and go to the corresponding conversion page at our website.

Bytes (B)

Convert bytes.
Byte is the base unit of data.
1 byte = 8 bits.

Kilobytes (KB)

Convert kilobytes.
1 Kilobyte = 1000¹ bytes in SI
1 Kilobyte = 1024¹ = 2¹⁰ bytes in binary

Megabytes (MB)

Convert megabytes.
1 Megabyte = 1000² bytes in SI
1 Megabyte = 1024² = 2²⁰ bytes in binary

Data Transfer Rate

Convert data transfer rate units.
Gbps, Mbps, kbps, MB/s, kB/s.

Gigabytes (GB)

Convert gigabytes.
1 Gigabyte = 1000³ bytes in SI
1 gigabyte = 1024³ = 2³⁰ bytes in binary

Terabytes (TB)

Convert terabytes.
1 Terabyte = 1000⁴ bytes in SI
1 Terabyte = 1024⁴ = 2⁴⁰ bytes in binary

Petabytes (PB)

Convert petabytes.
1 Petabyte = 1000⁵ bytes in SI
1 Petabyte = 1024⁵ = 2⁵⁰ bytes in binary

Megabytes and Gigabytes

How many bytes are in a megabyte?

There are 1,048,576 bytes in one megabyte in the binary system which computers use. But also, there are one million bytes in 1 MB according to the decimal system or base 10. In base 10, one megabyte is equivalent to 10*6 Bytes. On the other hand, in binary system or base 2, one megabyte is equal to 2*20 Bytes.

The unit symbol of Megabyte is MB; the unit symbol of Byte is B. And one megabyte is one million times bigger than a Byte.

Check this our online tool to convert Megabytes to Bytes easily.

What is the difference between MB and KB?

A kilobyte is a multiple of the unit for digital information with the prefix Kilo. A kilobyte consists of 1000 bytes, but in a computer system, a kilobyte refers to 1,024 bytes. Today a kilobyte contains little information, so storage capacities of computer hardware are mostly given in gigabytes and terabytes.

A megabyte is a measurement unit of information in computer storage and processing. One megabyte consists of 1,000,000 bytes in base 10. Originally one megabyte wasn't one million bytes but 1,048,576 bytes. That also means 1 MB is equal to 2*20 bytes or 1024*2 bytes.
