Kilobits Per Second (Kbps) to Bytes Per Second (B/s) Converter
Type a value into the Kilobits Per Second (Kbps) field to convert to Bytes Per Second (B/s). 1 Kbps = 125 B/s, covering both bit-based and byte-based transfer rate units.

How to Convert Kilobits Per Second to Bytes Per Second
To convert kilobits per second to bytes 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. See also: B/s to Kbps.
Kbps is a bit-based bandwidth commonly used for Dial-up internet, audio streaming, VoIP calls. When you see your ISP advertise speeds in Kbps, this is the raw network bandwidth. You might also need: Kilobits Per Second in Exabits Per Second.
B/s is what you actually experience when downloading files. Your browser, torrent client, or download manager shows speeds in B/s because that's how fast data is being written to your storage. See also: converting Tebibytes Per Second to Bytes Per Second.
1 Kbps = 125 B/s — which means there are 125bytes per second in every kilobit per second.
Kbps to B/s Conversion Formula
// Convert Kbps to B/s
B/s = Kbps × 125
// Reverse: Convert B/s to Kbps
Kbps = B/s × 0.008
Kbps to B/s Conversion Examples
10 Kbps = 1,250 B/s
50 Kbps = 6,250 B/s
100 Kbps = 12,500 B/s
500 Kbps = 62,500 B/s
1,000 Kbps = 125,000 B/s
What Is Kilobit Per Second (Kbps)?
A kilobit per second is 1,000 bits per second. Common for dial-up and low-speed connections. Related: GiB/s to Pbps conversion rate.
The kilobit per second is a bit-based bandwidth unit measuring data transfer speed, network bandwidth, or throughput capacity. See also: calculate PB to ZiB.
Common uses: Dial-up internet, audio streaming, VoIP calls Try the how many Gigabits Per Second in a Kbps.
1 Kbps = 1 × 10³ bits per second.
The kilobit per second can be abbreviated as Kbps; for example, 1 kilobit per second can be written as 1 Kbps.
What Is Byte Per Second (B/s)?
One byte (8 bits) transferred per second. The fundamental byte-based transfer rate. Related: how many B/s in Megabits Per Second.
The byte per second is a byte-based throughput unit measuring data transfer speed, network bandwidth, or throughput capacity. Learn more: Pebibits Per Second to TiB/s.
Common uses: File transfer displays, storage benchmarks, precise measurements See also: convert Zib to Nibbles.
1 B/s = 8 bits per second.
The byte per second can be abbreviated as B/s; for example, 1 byte per second can be written as 1 B/s.

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