Kibit/s to MB/s
1 kibibit per second equals 0.000128 megabytes per second exactly.
How to convert kibibits per second to megabytes per second
To convert kibibits per second to megabytes per second, multiply the number of kibibits per second by 0.000128. This factor is exact. To go the other way, multiply megabytes per second by 7,812.5.
megabytes per second = kibibits per second × 0.000128
Example: 10 kibibits per second = 0.00128 megabytes per second.
Network speeds are quoted in bits per second (lowercase b), while file sizes use bytes (uppercase B). Divide Mbps by 8 for MB/s.
About these units
Kibibit Per Second (Kibit/s)
1,024 bits per second.
Kibibit per second is the smallest of the binary data-rate units on the site, and its name shows how it was built. The prefix kibi keeps the first two letters of kilo and adds bi for binary. It stands for 2 to the power 10, which is 1,024. The International Electrotechnical Commission approved the prefix in December 1998 and published it in January 1999 as an amendment to IEC 60027-2.
One kibibit per second is exactly 1,024 bits per second, or 128 bytes per second at 8 bits to the byte. A kilobit per second in the decimal sense is 1,000 bits per second, so the binary unit is 2.4 percent larger. Network speeds are almost always quoted with decimal prefixes, so this unit turns up mostly where a rate is derived from binary-sized buffers or memory blocks.
1 kibibit per second = 1,024 bits per second (exactly).

Megabyte Per Second (MB/s)
1,000,000 bytes per second (8 Mbps). Disk and download speeds are shown in MB/s.
Megabytes per second inherit all the confusion of the megabyte itself. The word has meant 1,000,000 bytes in networking, hard drives and DVDs, 1,048,576 bytes for memory under Microsoft Windows, and 1,024,000 bytes for the 3.5-inch floppy disk marketed as 1.44 MB, which actually held 1,474,560 bytes. In 1999 the IEC defined megabyte as 10⁶ bytes and mebibyte as 2²⁰ bytes, and by the end of 2009 the IEEE, EU, ISO and NIST had adopted that standard.
As a rate, 1 MB/s is 1,000,000 bytes per second, or 8 Mbit/s. File copies, game installers and disk benchmarks usually show MB/s, while internet plans use Mbit/s, so a 100 Mbit/s plan tops out near 12.5 MB/s. As a feel for size, about one minute of 128 kbit/s MP3 audio fits in roughly 1 MB, so a link carrying 1 MB/s moves about a minute of such audio every second.
1 megabyte per second = 8,000,000 bits per second (exactly).
