Step-by-Step
How to Convert a Gigabyte to Gibibyte
If you want to manually convert a gigabyte to gibibyte without using the tool, you just need a standard calculator and the right formula.
The Method
A gigabyte (GB) uses a base-10 system, meaning exactly one billion bytes. A gibibyte (GiB) uses a base-2 system, which equals 1,073,741,824 bytes. To move between the two, you need a precise multiplier.
To make it easy: just multiply the number of gigabytes you have by 0.9313225746.
How to Turn Gigabytes into Gibibytes
Write the gigabyte value
Take the number of gigabytes you want to convert. For example, let's use 100.
Use the multiplier
Multiply the gigabyte value by 0.9313225746 to convert it into gibibytes.
Read the result
100 × 0.9313225746 = 93.13225746. So 100 GB equals roughly 93.13 GiB.
Storage Meaning
What Does GB Mean? (Gigabytes vs. Gibibytes)
If you've ever asked "what does GB mean?" or "whats a GB?", the answer is straightforward. It stands for gigabyte. The standard abbreviation for gigabyte (or gigabyte short form) is simply GB.
But how big is a GB in reality? In the standard decimal system used by most hard drive manufacturers and internet providers, 1 GB equals exactly one billion bytes.
However, operating systems like Windows read computer data in binary. This is where the gibibyte (GiB) comes in. Because a gibibyte is based on powers of 1024, it actually holds more bytes per unit than a standard gigabyte.
That is why when you convert gb to gib, the resulting number looks smaller. For example, a hard drive advertised as 500 GB will show up as about 465 GiB when you plug it into your computer.
Worked Examples
Sample GB to GiB Calculations
Here is how to convert commonly searched gigabyte values into their exact gibibyte equivalents.
1 gigabyte to gibibytes
1 × 0.9313225746 = 0.931323 GiB. One GB equals just under one full GiB.
10 gigabytes to gibibytes
10 × 0.9313225746 = 9.313226 GiB. Ten GB equals about 9.31 GiB.
64 gigabytes to gibibytes
64 × 0.9313225746 = 59.604645 GiB. Common on flash drives, 64 GB displays as roughly 59.6 GiB.
100 gigabytes to gibibytes
100 × 0.9313225746 = 93.132257 GiB. A solid 100 GB translates to 93.13 GiB.
500 gigabytes to gibibytes
500 × 0.9313225746 = 465.661287 GiB. If you buy a 500 GB drive, your OS will see it as about 465.6 GiB.
