Megabit Per Second (Mbps)
A megabit per second is 1,000,000 bits per second. The standard unit for home internet speeds.

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 Megabits Per Second to Kilobytes Per Second
To convert megabits per second to kilobytes 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.
Mbps is a bit-based bandwidth commonly used for Home internet speeds, WiFi connections, streaming video quality. When you see your ISP advertise speeds in Mbps, 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: Megabits Per Second to Megabytes Per Second.
1 Mbps = 125 KB/s — which means there are 125kilobytes per second in every megabit per second.
Mbps to KB/s transfer rate: 1 megabit per second equals 125kilobytes per second — the standard bandwidth conversion rate used by this data transfer calculator.

Mbps to KB/s Conversion Formula
Here's the exact Mbps to KB/s formula in copy-paste-ready form — multiply by 125 to go from megabits per second to kilobytes per second, or by 0.008 to reverse it — followed by a quick-reference chart of the same rate conversion.
// Convert Mbps to KB/s
KB/s = Mbps × 125
// Reverse: Convert KB/s to Mbps
Mbps = KB/s × 0.008
Megabit Per Second to Kilobyte Per Second Conversion Examples
10 Mbps = 1,250 KB/s
50 Mbps = 6,250 KB/s
100 Mbps = 12,500 KB/s
500 Mbps = 62,500 KB/s
1,000 Mbps = 125,000 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 Megabit Per Second (Mbps)? Definition and Uses
A megabit per second is 1,000,000 bits per second. The standard unit for home internet speeds.
The megabit 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: Home internet speeds, WiFi connections, streaming video quality See also: Petabytes Per Second to Terabytes Per Second.
1 Mbps = 1 × 10⁶ bits per second .
The megabit per second can be abbreviated as Mbps; for example, 1 megabit per second can be written as 1 Mbps.
Don't confuse Mbps with MB/s (Megabyte Per Second) — capitalization matters here. Mbps measures bits, MB/s measures bytes, and since 1 byte = 8 bits, 1 Mbps works out to just 0.125 MB/s using the same numeral.

What Is Kilobyte Per Second (KB/s)? Definition and Uses
A kilobyte per second is 1,000 bytes per second. Common display for file downloads.
The kilobyte per second is a byte-based throughput 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: Download progress displays, file transfer speeds, browser downloads
