How many MBs equal a GB?

Question:

How many MBs equal a GB?

Answer and Explanation:

MB stands for megabytes, and GB stands for gigabytes. Both are units to measure memory in computer systems.

Conventionally speaking, 1 MB = 1,000,000 bytes and 1 GB = 1,000,000,000 bytes. Hence, 1 GB = 1,000 MB.

But in reality, a computer system uses binary language, or a language of 0s and 1s. Each one of them is called a bit. 1 byte of memory can store 8 bits of data, or 23 bits. So the storage is calculated in powers of 2. This means that 1 KB, or 1 kilobyte, is not really 1,000 bytes. Rather, 1 KB = 1,024 bytes (210).

Similarly:

  • 1 MB = 220 bytes
  • 1 GB = 230 bytes

Therefore, in reality, 1 GB = 1,024 MB (210 MB).
