Kilobytes Per Second (KB/s) to Bytes Per Second (B/s) Converter
Type a value into the Kilobytes Per Second (KB/s) field to convert to Bytes Per Second (B/s). 1 KB/s = 1,000 B/s, covering both bit-based and byte-based transfer rate units.

How to Convert Kilobytes Per Second to Bytes Per Second
To convert kilobytes per second to bytes per second, multiply by 1,000. Both units measure actual data throughput in bytes per second—useful for comparing storage benchmarks, file transfer speeds, and backup performance. Check out our how many Kilobytes Per Second in a B/s.
KB/s: A kilobyte per second is 1,000 bytes per second. Common display for file downloads. Common uses include Download progress displays, file transfer speeds, browser downloads. You might also need: how many ZB/s in Kilobytes Per Second.
B/s: One byte (8 bits) transferred per second. The fundamental byte-based transfer rate. Typically used for File transfer displays, storage benchmarks, precise measurements. Use our Bits Per Second to B/s.
1 KB/s = 1,000 B/s — which means there are 1,000bytes per second in every kilobyte per second.
KB/s to B/s Conversion Formula
// Convert KB/s to B/s
B/s = KB/s × 1,000
// Reverse: Convert B/s to KB/s
KB/s = B/s × 0.001
KB/s to B/s Conversion Examples
10 KB/s = 10,000 B/s
50 KB/s = 50,000 B/s
100 KB/s = 100,000 B/s
500 KB/s = 500,000 B/s
1,000 KB/s = 1,000,000 B/s
What Is Kilobyte Per Second (KB/s)?
A kilobyte per second is 1,000 bytes per second. Common display for file downloads. Use our convert Tbps to Gigabits Per Second.
The kilobyte per second is a byte-based throughput unit measuring data transfer speed, network bandwidth, or throughput capacity. You might also need: Tebibits to B calculator.
