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

A petabyte per second is 1,000 terabytes per second. Used for supercomputer storage and hyperscale systems.

To convert terabits per second to petabytes per second, divide by 8,000 (or multiply by 0.000125). 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.
PB/s is what you actually experience when downloading files. Your browser, torrent client, or download manager shows speeds in PB/s because that's how fast data is being written to your storage. Related: Terabits Per Second to Terabytes Per Second.
1 Tbps = 0.000125 PB/s — or equivalently, 1 PB/s = 8,000Tbps.
Tbps to PB/s transfer rate: 1 terabit per second equals 0.000125petabytes 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 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.
