Gigabit Per Second (Gbps)
A gigabit per second is 1,000 megabits per second. Used for fiber internet and enterprise networking.

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 Gigabits Per Second to Kilobytes Per Second
To convert gigabits per second to kilobytes per second, divide by 0.000008 (or multiply by 125,000). This conversion accounts for the 8:1 relationship between bits and bytes—network speeds are measured in bits, while file sizes use bytes.
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.
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: Gigabits Per Second to Bytes Per Second.
1 Gbps = 125,000 KB/s — which means there are 125,000kilobytes per second in every gigabit per second.
Gbps to KB/s transfer rate: 1 gigabit per second equals 125,000kilobytes per second — the standard bandwidth conversion rate used by this data transfer calculator.

Gbps to KB/s Conversion Formula
Here's the exact Gbps to KB/s formula in copy-paste-ready form — multiply by 125,000 to go from gigabits per second to kilobytes per second, or by 0.000008 to reverse it — followed by a quick-reference chart of the same rate conversion.
// Convert Gbps to KB/s
KB/s = Gbps × 125,000
// Reverse: Convert KB/s to Gbps
Gbps = KB/s × 0.000008
Gigabit Per Second to Kilobyte Per Second Conversion Examples
10 Gbps = 1,250,000 KB/s
50 Gbps = 6,250,000 KB/s
100 Gbps = 12,500,000 KB/s
500 Gbps = 62,500,000 KB/s
1,000 Gbps = 125,000,000 KB/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 Gigabit Per Second (Gbps)? Definition and Uses
A gigabit per second is 1,000 megabits per second. Used for fiber internet and enterprise networking.
The gigabit 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: Fiber internet, enterprise networks, data center connections, 10GbE See also: Gigabits Per Second to Zettabits Per Second.
1 Gbps = 1 × 10⁹ bits per second .
The gigabit per second can be abbreviated as Gbps; for example, 1 gigabit per second can be written as 1 Gbps.
Don't confuse Gbps with GB/s (Gigabyte Per Second) — capitalization matters here. Gbps measures bits, GB/s measures bytes, and since 1 byte = 8 bits, 1 Gbps works out to just 0.125 GB/s using the same numeral.
