How to Convert Gigabits Per Second to Gigabytes Per Second
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. See also: GB/s → Gbps.
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. Related: convert Gbps to Ebps.
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. Learn more: EB/s to GB/s calculator.
1 Gbps = 0.125 GB/s — or equivalently, 1 GB/s = 8Gbps.
Gbps to GB/s Conversion Formula
// Convert Gbps to GB/s
GB/s = Gbps × 0.125
// Reverse: Convert GB/s to Gbps
Gbps = GB/s × 8
Gbps to GB/s 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
What Is Gigabit Per Second (Gbps)?
A gigabit per second is 1,000 megabits per second. Used for fiber internet and enterprise networking. Check out our Kbps to KiB/s converter.
The gigabit per second is a bit-based bandwidth unit measuring data transfer speed, network bandwidth, or throughput capacity. Learn more: KB to YiB.

Bits vs Bytes: Understanding Network Speed vs Download Speed
The difference between bits and bytes is crucial when working with gigabits per second and gigabytes per second:
| Unit Type | Symbol | Used For |
|---|---|---|
| Bits per second | Mbps, Gbps | ISP speeds, network bandwidth, WiFi specs |
| Bytes per second | MB/s, GB/s | Download managers, file transfers, SSD speeds |
Quick Conversion Rule
Divide bits by 8 to get bytes. Your "100 Mbps" internet connection delivers a maximum of 12.5 MB/s actual download speed.
Real-world speeds are typically 70-85% of theoretical maximum due to protocol overhead, network congestion, and other factors.
💡 Storage Engineer Tip
Divide bits by 8 to get bytes. When your ISP advertises "100 Mbps," your maximum download speed is 12.5 MB/s. Real-world speeds are typically 70-85% of theoretical maximum due to protocol overhead.
