Definition of Megabit Per Second

Definition
Megabit per second (Mbps) measures data transfer speed at 1,000,000 bits per second. It is the standard unit used by ISPs to advertise internet connection speeds.

Important: Mbps (megaBITS) is not the same as MB/s (megaBYTES). 1 MB/s = 8 Mbps.
Exact factor
1 Mbps = 1,000,000 bps = 1,000 Kbps = 0.001 Gbps
Examples
• 4K streaming: 25+ Mbps
• Typical home internet: 50–300 Mbps

Definition of Kilobyte Per Second

Definition
Kilobyte per second (KB/s) measures data transfer at 8,000 bits per second. Common in legacy systems and very slow connections.
Exact factor
1 KB/s = 8 Kbps = 8,000 bps
Examples
• Dial-up max: ~7 KB/s (56 Kbps)

About the Megabit-per-second

Facts & Uses

  • Mbps is the universal unit for internet speed — every ISP worldwide advertises in Mbps or Gbps.
  • The average US internet speed in 2024 is about 242 Mbps (Ookla Speedtest).
  • Netflix recommends 5 Mbps for HD, 15 Mbps for 4K, and 25 Mbps for 4K HDR.

Curiosities

  • The first dial-up modems ran at 0.0003 Mbps (300 bps). Today's 10 Gbps fiber is 33 million times faster.
  • A 1 Gbps connection can theoretically download the entire English Wikipedia (~22 GB) in under 3 minutes.

Frequently Asked Questions

How many kilobyte-per-seconds are in one megabit-per-second?

One megabit-per-second equals 125 kilobyte-per-seconds. To convert, multiply the megabit-per-second value by 125. For the reverse, divide the kilobyte-per-second value by 125 (or multiply by 0.008).

What is 10 megabit-per-seconds in kilobyte-per-seconds?

10 megabit-per-seconds = 1250 kilobyte-per-seconds. This is one of the most commonly searched conversions for this pair.

How precise is the megabit-per-second-to-kilobyte-per-second conversion?

The factor 125 is accurate to 6 significant figures, derived from international measurement standards. Our calculator uses full precision internally.
