# Megabytes vs 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.

**Megabytes vs Gigabytes**

A megabyte is a unit of digital information consists of one million (base 10) or, 2*20 bytes (base 2). A gigabyte is a unit of digital information consists of one thousand million (base 10) or, 2*30 bytes (base 2).

One megabyte is equivalent to 1000*2 bytes or 8,000,000 bits; one gigabyte is equal to 1000*3 bytes or 8,000,000,000 bits.

A Gigabyte is much greater than a Megabyte. There are 1000 MB (in decimal) or 1024 MB (in binary). So one Gigabyte is one thousand times bigger than one Megabyte.
