Step-by-Step
How to Convert a GiB to Gigabyte
Calculating a gibibyte to gigabyte conversion is easy once you know the exact multiplier.
The Conversion Formula
To translate a binary unit (GiB) into a decimal unit (GB), you multiply your starting value by roughly 1.074. The exact math is:
Because of this multiplier, your resulting number of gigabytes will always be slightly higher than the number of gibibytes you started with.
How to Calculate GiB to GB
Identify your value
Find the number of gibibytes you want to convert. For instance, you might have an 8 GiB file.
Multiply the number
Multiply that value by the specific decimal: 1.073741824.
You have your answer
8 × 1.073741824 = 8.589934592. That means your 8 GiB file is roughly 8.59 gigabytes.
Understanding Storage
What is a GiB? Understanding GiB vs GB
If you have ever bought a hard drive and noticed it shows less space on your computer than advertised on the box, you have encountered the difference between a GiB and a GB. So, what is a GiB exactly?
The meaning of a gibibyte (GiB) is a unit of digital data based on binary math (powers of 2). In computer architecture, 1 GiB equals exactly 1,073,741,824 bytes.
In contrast, a standard gigabyte (GB) uses decimal math (powers of 10). Storage manufacturers prefer this because 1 GB is an even 1,000,000,000 bytes.
Because computers naturally operate in binary, operating systems like Windows read storage memory in gibibytes, even though they might confusingly label it as "GB". When you convert 1 GiB to GB, you are accounting for those extra 73 million bytes.
Worked Examples
Common GiB to GB Conversions
Here is how to calculate out some of the most frequent storage sizes you might run into.
1 GiB to GB
1 × 1.073741824 = 1.073741824 GB. A single gibibyte gives you roughly 1.07 gigabytes.
2 GiB to GB
2 × 1.073741824 = 2.147483648 GB. Two gibibytes translates to about 2.15 gigabytes.
4 GiB to GB
4 × 1.073741824 = 4.294967296 GB. Four gibibytes is just over 4.29 GB.
8 GiB to GB
8 × 1.073741824 = 8.589934592 GB. If your RAM is 8 GiB, it holds about 8.59 standard gigabytes of data.
10 GiB to GB
10 × 1.073741824 = 10.73741824 GB. Ten gibibytes yields roughly 10.74 gigabytes.
16 GiB to GB
16 × 1.073741824 = 17.179869184 GB. Sixteen gibibytes provides a bit over 17 GB.
32 GiB to GB
32 × 1.073741824 = 34.359738368 GB. Thirty-two gibibytes is more than 34 gigabytes.
100 GiB to GB
100 × 1.073741824 = 107.3741824 GB. One hundred gibibytes comes out to roughly 107.37 GB of storage.
