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
Why Does the Difference Between GB and GiB Matter?
This is the conversion that explains the "missing" storage on new drives. When you buy a 500 GB hard drive, the manufacturer measures using the decimal system. Your computer's operating system often reports the same drive as about 465 GiB because it counts using powers of 1,024 instead of 1,000. Nothing is wrong with the drive — the two numbers just use different scales.
The gap grows as drives get bigger. A 1 TB drive (1,000 GB) shows up as roughly 931 GiB. A 2 TB drive appears as about 1,863 GiB. Understanding this conversion saves you from thinking your drive is defective or that the manufacturer shorted you on space.
Cloud providers, RAM specifications, and some Linux distributions report storage in gibibytes. Knowing the exact conversion helps you compare apples to apples across different platforms. For the reverse calculation, use our gibibytes to gigabytes converter.
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.
1000 gigabytes to gibibytes
1000 × 0.9313225746 = 931.322575 GiB. One terabyte (1000 GB) converts to roughly 931 GiB.
