  • Use KiB, MiB, and GiB when a value is explicitly based on powers of 1,024.
  • Check the unit label before comparing an operating system report with advertised drive capacity.

Quick answers

How many MB are in one GB?

One decimal gigabyte equals 1,000 megabytes. This is the convention commonly used for drive capacity and network transfer sizes.

How many MiB are in one GiB?

One gibibyte equals 1,024 mebibytes because binary storage units use powers of 1,024.

What is the difference between GB and GiB?

A GB is 1,000,000,000 bytes. A GiB is 1,073,741,824 bytes. They are different units, even though software sometimes labels them inconsistently.

Is one KB 1,000 or 1,024 bytes?

One kilobyte is 1,000 bytes. The binary unit for 1,024 bytes is a kibibyte, abbreviated KiB.
