Terabit Per Second (Tbps)
A terabit per second is 1,000 gigabits per second. Used for backbone networks and data center interconnects.

A kilobyte per second is 1,000 bytes per second. Common display for file downloads.
View the kilobyte per second data unit pageHow to Convert Terabits Per Second to Kilobytes Per Second
To convert terabits per second to kilobytes per second, divide by 0.000000008 (or multiply by 125,000,000). 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.
KB/s is what you actually experience when downloading files. Your browser, torrent client, or download manager shows speeds in KB/s because that's how fast data is being written to your storage. Related: Terabits Per Second to Bytes Per Second.
1 Tbps = 125,000,000 KB/s — which means there are 125,000,000kilobytes per second in every terabit per second.
Tbps to KB/s transfer rate: 1 terabit per second equals 125,000,000kilobytes per second — the standard bandwidth conversion rate used by this data transfer calculator.

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: Terabits Per Second to Yottabits 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.

SI Decimal Prefixes: How Tbps to KB/s Is Calculated
Both terabits per second and kilobytes per second are SI decimal units, so every prefix step is exactly 1,000 and 1 Tbps = 125,000,000 KB/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 |
|---|---|---|---|
| Terabit Per Second (Tbps) | SI decimal | 1,000 | 1,000,000,000,000 bps |
| Kilobyte Per Second (KB/s) | SI decimal | 1,000 | 8,000 bps |

6 questions Quick answers on converting terabits per second to kilobytes per second, using the same factors as the converter above.
-
How many kilobytes per second are in 1 terabit per second?
1 Tbps = 125,000,000 KB/s
1 Terabit Per Second (Tbps) equals 125,000,000 Kilobytes Per Second.
-
How many terabits per second are in 1 kilobyte per second?
1 KB/s = 0.000000008 Tbps
1 Kilobyte Per Second (KB/s) equals 0.000000008 Terabits Per Second.
-
How do I convert terabits per second to kilobytes per second?
Tbps × 125,000,000 = KB/s
Multiply the terabit per second value by 125,000,000 to get kilobytes per second. For example, 10 Tbps = 1,250,000,000 KB/s. To convert back (vice versa), multiply kilobytes per second by 0.000000008.
-
What is the difference between terabits per second and kilobytes per second?
Tbps measures network bandwidth in bits per second, while KB/s measures actual transfer throughput in bytes per second. Divide bits by 8 to get bytes.
-
Does Tbps to KB/s use SI decimal or binary prefixes?
Base 10 (SI): 1,000 per step
Both terabits per second and kilobytes per second are SI decimal (base 10) units, so each prefix step is exactly 1,000, giving 1 Tbps = 125,000,000 KB/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 Terabit Per Second (Tbps) commonly used for?
Common uses of the terabit per second (Tbps) include: Backbone networks, submarine cables, data center fabrics, high-speed interconnects.
