Questions about this tool

How many gigabytes are in one gibibyte?

1 GiB = 1.07374 GB exactly.

How do I convert gibibytes to gigabytes?

Use GB = GiB × 1.073741824. For example, 25 GiB = 26.8435 GB.

How many gibibytes are in one gigabyte?

1 GB = 0.931323 GiB.

Why does a 1 TB drive show about 931 GB on my computer?

Drive makers count 1 TB as 10^12 bytes, while Windows divides by 2^30 and labels the result GB even though it is really GiB. So 10^12 ÷ 1,073,741,824 gives about 931.32, and no space is missing.

What is the difference between a kilobyte and a kibibyte?

A kilobyte (kB) is a decimal unit of 1000 bytes and a kibibyte (KiB) is a binary unit of 1024 bytes. The same split applies to mega and mebi, giga and gibi, and the gap grows at each step.
