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.
Byte is the base unit of data.
1 byte = 8 bits.
1 Kilobyte = 10001 bytes in SI
1 Kilobyte = 10241 = 210 bytes in binary
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.
1 Gigabyte = 10003 bytes in SI
1 gigabyte = 10243 = 230 bytes in binary
1 Terabyte = 10004 bytes in SI
1 Terabyte = 10244 = 240 bytes in binary
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.
