To convert gigabits per second to gigabytes per second, divide by 8 (or multiply by 0.125). This conversion accounts for the 8:1 relationship between bits and bytes—network speeds are measured in bits, while file sizes use bytes.
Gbps is a bit-based bandwidth commonly used for Fiber internet, enterprise networks, data center connections, 10GbE. When you see your ISP advertise speeds in Gbps, this is the raw network bandwidth.
GB/s is what you actually experience when downloading files. Your browser, torrent client, or download manager shows speeds in GB/s because that's how fast data is being written to your storage. Related: Gigabits Per Second to Terabytes Per Second.
1 Gbps = 0.125 GB/s — or equivalently, 1 GB/s = 8Gbps.
Gbps to GB/s transfer rate: 1 gigabit per second equals 0.125gigabytes per second — the standard bandwidth conversion rate used by this data transfer calculator.

Gbps to GB/s Conversion Formula
Here's the exact Gbps to GB/s formula in copy-paste-ready form — multiply by 0.125 to go from gigabits per second to gigabytes per second, or by 8 to reverse it — followed by a quick-reference chart of the same rate conversion.
// Convert Gbps to GB/s
GB/s = Gbps × 0.125
// Reverse: Convert GB/s to Gbps
Gbps = GB/s × 8
Gigabit Per Second to Gigabyte Per Second Conversion Examples
10 Gbps = 1.25 GB/s
50 Gbps = 6.25 GB/s
100 Gbps = 12.5 GB/s
500 Gbps = 62.5 GB/s
1,000 Gbps = 125 GB/s
Most data transfer rate units step by powers of ten: moving up the scale (bps → Kbps → Mbps → Gbps and beyond) means multiply by 1000, moving down means divide by 1000 — usually just a matter of shifting the decimal point. What's actually being counted underneath is bits: the binary digits, 0s and 1s, that make up every network signal.

SI Decimal Prefixes: How Gbps to GB/s Is Calculated
Both gigabits per second and gigabytes per second are SI decimal units, so every prefix step is exactly 1,000 and 1 Gbps = 0.125 GB/s. This is the convention behind advertised link speeds and drive specifications. Because one unit counts bits and the other bytes, the factor also includes a factor of 8.
| Unit | Standard | Prefix step | 1 unit equals |
|---|---|---|---|
| Gigabit Per Second (Gbps) | SI decimal | 1,000 | 1,000,000,000 bps |
| Gigabyte Per Second (GB/s) | SI decimal | 1,000 | 8,000,000,000 bps |

-
How many gigabytes per second are in 1 gigabit per second?
1 Gbps = 0.125 GB/s
1 Gigabit Per Second (Gbps) equals 0.125 Gigabytes Per Second.
-
How many gigabits per second are in 1 gigabyte per second?
1 GB/s = 8 Gbps
1 Gigabyte Per Second (GB/s) equals 8 Gigabits Per Second.
-
How do I convert gigabits per second to gigabytes per second?
Gbps × 0.125 = GB/s
Multiply the gigabit per second value by 0.125 to get gigabytes per second. For example, 10 Gbps = 1.25 GB/s. To convert back (vice versa), multiply gigabytes per second by 8.
-
What is the difference between gigabits per second and gigabytes per second?
Gbps measures network bandwidth in bits per second, while GB/s measures actual transfer throughput in bytes per second. Divide bits by 8 to get bytes.
-
Does Gbps to GB/s use SI decimal or binary prefixes?
Base 10 (SI): 1,000 per step
Both gigabits per second and gigabytes per second are SI decimal (base 10) units, so each prefix step is exactly 1,000, giving 1 Gbps = 0.125 GB/s. Because one unit counts bits and the other bytes, the factor also includes a factor of 8. The binary (IEC) versions count in base 2 steps of 1,024 instead.
-
What is Gigabit Per Second (Gbps) commonly used for?
Common uses of the gigabit per second (Gbps) include: Fiber internet, enterprise networks, data center connections, 10GbE.
