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.
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.
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: Terabits Per Second to Exabytes Per Second.
1 Tbps = 125 GB/s — which means there are 125gigabytes per second in every terabit per second.
Tbps to GB/s transfer rate: 1 terabit per second equals 125gigabytes per second — the standard bandwidth conversion rate used by this data transfer calculator.

Tbps to GB/s Conversion Formula
Here's the exact Tbps to GB/s formula in copy-paste-ready form — multiply by 125 to go from terabits per second to gigabytes per second, or by 0.008 to reverse it — followed by a quick-reference chart of the same rate conversion.
// Convert Tbps to GB/s
GB/s = Tbps × 125
// Reverse: Convert GB/s to Tbps
Tbps = GB/s × 0.008
Terabit Per Second to Gigabyte Per Second Conversion Examples
10 Tbps = 1,250 GB/s
50 Tbps = 6,250 GB/s
100 Tbps = 12,500 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.
What Is Terabit Per Second (Tbps)? Definition and Uses
A terabit per second is 1,000 gigabits per second. Used for backbone networks and data center interconnects.
The terabit per second is a bit-based bandwidth unit measuring data transfer speed, network bandwidth, or throughput capacity. Like the units used to measure file size, it's one of several data measurement units that scale using either decimal multiples of 1,000 (SI) or binary steps of 1,024 (IEC).
Common uses: Backbone networks, submarine cables, data center fabrics, high-speed interconnects See also: Exbibytes Per Second to Exabytes Per Second.
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.
Don't confuse Tbps with TB/s (Terabyte Per Second) — capitalization matters here. Tbps measures bits, TB/s measures bytes, and since 1 byte = 8 bits, 1 Tbps works out to just 0.125 TB/s using the same numeral.
