Free online data transfer rate converter

Data transfer rate measures how fast data moves across a network or storage device. This converter handles both SI (1000-based) and IEC (1024-based) units used in networking and.

Worked example

Your home internet connection is 500 Mbps.

Converting to kbps: 500 × 1000 = 500 000 kbps

Converting to MB/s: 500 ÷ 8 = 62.5 MB/s (megabytes per second)

Notes

  • SI prefixes (kilo-, mega-, giga-) use powers of 1000 in networking standards (IEC 80000-13).
  • IEC binary prefixes (kibi-, mebi-, gibi-) use powers of 1024, common in some storage contexts.
  • 1 byte = 8 bits by definition; B/s and kB/s use this 8× multiplier.

Frequently asked

How does the data rate converter work?
Every unit is first converted to the base unit (bits per second) by multiplying by a fixed factor, then divided by the target unit's factor to get the result.
What is the difference between Mbps and MBps?
Mbps means megabits per second (1 000 000 bits/s). MBps means megabytes per second, which is 8× larger. Internet speeds are typically advertised in Mbps while file transfer speeds often display in MBps.
What is the difference between kilobits and kibibits?
Kilobits (kbps) uses the SI prefix: 1 kbps = 1000 bps. Kibibits (Kibps) uses the IEC binary prefix: 1 Kibps = 1024 bps. Networking hardware typically uses SI while some memory specs use IEC.
How many kbps is 1 Mbps?
1 Mbps = 1000 kbps (using SI prefixes). Networks are rated in SI units.
What units are supported?
Bits per second (bps), kilobits/s (kbps), megabits/s (Mbps), gigabits/s (Gbps), terabits/s (Tbps), kibibits/s (Kibps), mebibits/s (Mibps), gibibits/s (Gibps), bytes per second (B/s), and kilobytes per second (kB/s).
