### How Many MB in a GB?

If you literally just want the answer to the question you just asked, there are 1024MB (megabytes) in one GB (gigabyte). If you want to know more there are 1024 gigabytes in a terabyte (TB) and 1024 terabytes in one petabyte (PB).

## What's a megabyte?

Computer storage is measured in gigabytes (GB) and terabytes (TB), among other units. Your phone will have a number of gigabytes in which to store apps, music, contacts, emails, messages, photos, videos and more.

Don't confuse storage with memory. Memory, or RAM, is there only to store files and data temporarily while they're being used. That's why the amount of memory is much smaller - a phone might have 128GB of storage but only 4GB of memory (RAM).

Here's how it all works:

• 1TB = 1024GB
• 1GB = 1024MB
• 1MB = 1024KB
• 1kB = 1024 Bytes
• 1 Byte = 8 bits
• 1 bit = 0 or 1

Bit: Computers deal with binary digits, or bits for short. A bit can be 0 or 1, equivalent or off or on.

Byte: One byte is eight binary digits, such as 1111001.

Kilobyte (kB): The smallest file stored on a smartphone, tablet or PC is typically four kilobytes (4KB) in size. A kiloByte is 1024 Bytes. Therefore 1KB is the same as 1024 x 8 = 8192 binary digits.

Megabyte (MB): 1024KB equals one megabyte (MB).

Gigabyte (GB): There are 1024MB in one gigabyte.

Terabyte (TB): There are 1024GB in one terabyte (TB)
