How to convert gibibytes to gigabytes
To convert gibibytes (GiB) to gigabytes (GB), multiply the value in gibibytes by 1.073741824.
GB = GiB × 1.073741824 (decimal)
GB = GiB × 1 (binary)
Example: 5 GiB = 5.36870912 GB, or 5 GB in binary.
Decimal (SI) counting steps by 1,000 and is what drive makers, macOS and phones use. Binary counting steps by 1,024 and is what Windows and RAM use; its unambiguous IEC names are KiB, MiB and GiB. Bits are decimal either way.
You can also type 5 GiB to GB into the smart calculator, or mix units: 1 GiB + 1 GB.

About the units
Gibibyte (GiB)
Exactly 1,073,741,824 bytes, or 1,024 MiB. What Windows displays as GB.
Gigabyte (GB)
In decimal mode 1,000,000,000 bytes (1,000 MB); in binary mode 1,073,741,824 bytes (1,024 MB).
Digital storage is counted in bits and bytes (1 byte = 8 bits). There are two ways to count bytes. Decimal (SI) prefixes step by 1,000: 1 KB = 1,000 B and 1 GB = 1,000 MB, which is how drive makers, macOS, iOS and Android report sizes. Binary prefixes step by 1,024: 1 KB = 1,024 B and 1 GB = 1,024 MB, which is how Windows and RAM count (the IEC names for these are KiB, MiB and GiB). Bits are always decimal: 1 Kb = 1,000 b.
Questions and answers
How many gigabytes are in a gibibyte?
One gibibyte (GiB) equals 1.073741824 gigabytes in decimal (SI) counting, or 1 gigabytes in binary counting (1 KB = 1,024 B), which Windows uses.
How do I convert gibibytes to gigabytes?
To convert gibibytes to gigabytes, multiply the value in gibibytes by 1.073741824. The formula is GB = GiB × 1.073741824. For example, 5 GiB = 5.3687091 GB.
What is 5 GiB in GB?
5 gibibytes is 5.36870912 gigabytes.
Which is bigger, a gibibyte or a gigabyte?
A gibibyte is bigger: 1 GiB = 1.073741824 GB.
Is 1 GB equal to 1,000 MB or 1,024 MB?
Both are in use. In decimal (SI) counting, which drive makers, macOS, iOS and Android use, 1 GB = 1,000 MB. In binary counting, which Windows and RAM use, 1 GB = 1,024 MB; the unambiguous IEC name for that size is the gibibyte (GiB). ConvertEasy has a Decimal / Binary switch so KB, MB, GB and TB follow whichever you need, while KiB, MiB and GiB are always binary.
Are kilobits 1,000 or 1,024 bits?
ConvertEasy treats bits as decimal in both modes: 1 Kb = 1,000 b, 1 Mb = 1,000 Kb. A byte is always 8 bits, so only byte units (KB, MB, GB…) change with the switch.
Does this GiB to GB converter work offline?
Yes. ConvertEasy is a progressive web app: after your first visit it keeps working with no connection, and you can install it to your home screen from the browser menu.
