How to Convert Terabits Per Second to Gigabytes Per Second
To convert terabits per second to gigabytes per second, divide by 0.008 (or multiply by 125). This conversion accounts for the 8:1 relationship between bits and bytes—network speeds are measured in bits, while file sizes use bytes. Use our Gigabytes Per Second to Terabits Per Second.
Tbps is a bit-based bandwidth commonly used for Backbone networks, submarine cables, data center fabrics, high-speed interconnects. When you see your ISP advertise speeds in Tbps, this is the raw network bandwidth. Related: Tbps → B/s.
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. Try the convert Gibps to GB/s.
1 Tbps = 125 GB/s — which means there are 125gigabytes per second in every terabit per second.
Tbps to GB/s Conversion Formula
// Convert Tbps to GB/s
GB/s = Tbps × 125
// Reverse: Convert GB/s to Tbps
Tbps = GB/s × 0.008
Tbps to GB/s Conversion Examples
10 Tbps = 1,250 GB/s
50 Tbps = 6,250 GB/s
100 Tbps = 12,500 GB/s
500 Tbps = 62,500 GB/s
1,000 Tbps = 125,000 GB/s
What Is Terabit Per Second (Tbps)?
A terabit per second is 1,000 gigabits per second. Used for backbone networks and data center interconnects. See also: YiB/s to GiB/s calculator.
The terabit per second is a bit-based bandwidth unit measuring data transfer speed, network bandwidth, or throughput capacity. You might also need: Mib to b converter.
Common uses: Backbone networks, submarine cables, data center fabrics, high-speed interconnects Use our Tbps to EiB/s.
1 Tbps = 1 × 10¹² bits per second.
The terabit per second can be abbreviated as Tbps; for example, 1 terabit per second can be written as 1 Tbps.
What Is Gigabyte Per Second (GB/s)?
A gigabyte per second is 1,000 megabytes per second. Used for NVMe SSDs and high-speed storage. Use our Exbibytes Per Second in Gigabytes Per Second.
The gigabyte per second is a byte-based throughput unit measuring data transfer speed, network bandwidth, or throughput capacity. You might also need: converting Kilobytes Per Second to Zettabytes Per Second.
Common uses: NVMe SSD speeds, PCIe bandwidth, high-performance computing, GPU memory Learn more: EiB to Gb conversion rate.
1 GB/s = 8 × 10⁹ bits per second.
The gigabyte per second can be abbreviated as GB/s; for example, 1 gigabyte per second can be written as 1 GB/s.

Bits vs Bytes: Understanding Network Speed vs Download Speed
The difference between bits and bytes is crucial when working with terabits 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.

When to Convert Tbps to GB/s
Common scenario: Converting network bandwidth to actual file transfer speed for download time estimates and capacity planning. You might also need: calculate Tbps to KiB/s.
Other situations include ISP speed verification for checking if you're getting advertised speeds, network planning for sizing links and capacity, backup window calculations for estimating transfer times, and replication sizing for disaster recovery planning.
