Frequently Asked Questions
A Gigabyte (GB) uses the base-10 decimal system (10^9), where 1GB = 1,000MB. A Gibibyte (GiB) uses the base-2 binary system (2^30), where 1GiB = 1,024MiB. Most operating systems use binary, while storage manufacturers use decimal.
According to the International System of Units (SI), there are exactly 1,000 Megabytes (MB) in 1 Gigabyte (GB). However, in computer science contexts using binary, you may be looking for 1,024 Mebibytes (MiB).
This is due to the difference between decimal and binary calculation. Manufacturers sell 1TB as 1,000,000,000,000 bytes. Windows divides this by 1024 three times (to get GiB), resulting in the 931.32 GiB you see on your screen.
While the Yottabyte (YB) is currently the highest officially recognized SI unit, terms like Brontobyte and Hellabyte are used to describe even larger scales of data (1,000 Yottabytes).
