Mbps to Kbps converter calculator

Last updated:

1 megabit per second (Mbps) equals 1,000 kilobits per second (kbps) in modern networking, where each prefix step is a factor of 1,000. So 100 Mbps = 100,000 kbps and 1 Gbps = 1,000,000 kbps.

Formula: 1 Mbps = 1,000 Kbps. Open the live calculator to convert any value.

Formula

1 Mbps = 1,000 Kbps

Network speeds use SI decimal prefixes (1 Mbps = 10^6 bits/s = 1,000 kbps), unlike file sizes which sometimes use binary prefixes (1 MiB = 1024 KiB). The IEC adopted the binary 'kibi/mebi/gibi' prefixes in 1998 to remove the ambiguity, but in casual usage the distinction is often dropped.

Background

Internet service providers quote speeds in Mbps using the decimal definition. A 100 Mbps plan is 100 million bits per second, not 104.86 million. The discrepancy between decimal Mbps and binary MiB matters when calculating download time from advertised speed vs file size.

Common use cases

  • Compare an ISP plan in Mbps with device or software labels that still show Kbps.
  • Translate video, audio, or VoIP bitrate settings into smaller units for troubleshooting.
  • Document bandwidth limits in the unit that a customer, vendor, or dashboard expects.

Frequently asked questions

How many kbps is 1 Mbps?

1 Mbps is 1,000 kbps in network terminology (using decimal SI prefixes).

Is Mbps the same as MBps?

No. Lowercase 'b' is bits, uppercase 'B' is bytes. 1 MBps (megabytes per second) is 8 Mbps (megabits per second). Internet speeds are usually quoted in Mbps; download managers often display MBps.

How fast is 100 Mbps in real terms?

100 Mbps is enough to stream 4K video on multiple devices simultaneously, run video calls, and download large files at around 12 MB/s.

Why does my real download speed look slower than the advertised Mbps?

Three reasons: byte/bit confusion (divide Mbps by 8 for MB/s), network overhead (~5-15%), and last-mile congestion. A 100 Mbps plan tops out near 12 MB/s in ideal conditions.

Is kilobit per second still relevant?

Mostly for legacy or constrained connections (satellite links, cellular fallbacks, IoT data plans) and for measuring audio streaming quality. Music streams range from 96 kbps (low) to 320 kbps (high MP3) to ~1,411 kbps (CD-quality FLAC).
