How to convert gigabits per second to gigabytes per second
To convert gigabits per second (Gbps) to gigabytes per second (GB/s), multiply the value in gigabits per second by 0.125.
GB/s = Gbps × 0.125 (decimal)
GB/s = Gbps × 0.116415321827 (binary)
Example: 5 Gbps = 0.625 GB/s, or 0.5820766091 GB/s 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 Gbps to GB/s into the smart calculator, or mix units: 1 Gbps + 1 GB/s.

About the units
Gigabit per second (Gbps)
A unit of bandwidth.
Gigabyte per second (GB/s)
A unit of bandwidth.
Network speeds are sold in bits per second, which are always decimal (1 Mbps = 1,000 kbps). Download dialogs show bytes per second, which some apps count in decimal (1 MB/s = 1,000 KB/s) and others in binary (1 MB/s = 1,024 KB/s). Because a byte is 8 bits, a 100 Mbps connection tops out around 12.5 MB/s (11.9 binary MB/s) before protocol overhead.
Questions and answers
How many gigabytes per second are in a gigabit per second?
One gigabit per second (Gbps) equals 0.125 gigabytes per second in decimal (SI) counting, or 0.1164153218 gigabytes per second in binary counting (1 KB = 1,024 B), which Windows uses.
How do I convert gigabits per second to gigabytes per second?
To convert gigabits per second to gigabytes per second, multiply the value in gigabits per second by 0.125. The formula is GB/s = Gbps × 0.125. For example, 5 Gbps = 0.625 GB/s.
What is 5 Gbps in GB/s?
5 gigabits per second is 0.625 gigabytes per second.
Which is bigger, a gigabit per second or a gigabyte per second?
A gigabyte per second is bigger: 1 GB/s = 8 Gbps.
Why is my download speed lower than my internet plan?
Plans are sold in megabits per second (Mbps) and downloads show megabytes per second (MB/s). A byte is 8 bits, so 100 Mbps is at most 12.5 MB/s, or 11.92 MB/s if your download manager counts in binary, and protocol overhead takes a little more.
Is 1 MB/s 1,000 KB/s or 1,024 KB/s?
It depends on the app. Decimal counting gives 1 MB/s = 1,000 KB/s; binary counting (common in Windows tools and some download managers) gives 1,024 KB/s. Use the Decimal / Binary switch to match your app. Bit rates like Mbps are always decimal.
Does this Gbps to GB/s 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.
