About This Conversion
Gigabytes to gibibytes is the conversion that explains most reported-capacity complaints. A gigabyte is 10⁹ bytes; a gibibyte is 2³⁰ bytes, which is 1,073,741,824. One GB is therefore 0.9313 GiB, a 6.9 percent difference.
The gap widens with every prefix step: about 2.4 percent at kilo, 4.9 at mega, 7.4 at giga and 10 at tera. That is why a 1 TB drive reports as 931 GiB while a 1 GB file barely looks different, and why RAM, which really is sold in binary units, matches its label exactly.
Frequently Asked Questions
How many GiB is 1 GB?
1 GB is about 0.9313 GiB.
How many GiB is 500 GB?
500 GB is about 465.66 GiB.
Why is RAM sized in binary but storage in decimal?
RAM is addressed in powers of two, so binary sizes are physical. Drive capacity has no such constraint, and manufacturers use decimal.
Is GiB bigger than GB?
Yes. A gibibyte is about 7.4 percent larger than a gigabyte.
