B/s to MiB/s
1 byte per second equals 9.536743164×10⁻⁷ mebibytes per second (rounded).
How to convert bytes per second to mebibytes per second
To convert bytes per second to mebibytes per second, multiply the number of bytes per second by 9.536743164×10⁻⁷. The factor is rounded to 10 significant digits. To go the other way, multiply mebibytes per second by 1,048,576.
mebibytes per second = bytes per second × 9.536743164×10⁻⁷
Example: 10 bytes per second = 0.000009536743164 mebibytes 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
Byte Per Second (B/s)
Eight bits per second.
Byte is a younger word than bit. Werner Buchholz coined it in June 1956 during the early design of the IBM Stretch computer, deliberately spelling it with a y so that nobody would mistake it for bit. At first it had no fixed size, and Stretch's early design allowed groups of one to six bits. Eight-bit bytes were then built into Stretch, and IBM's System/360 spread them widely in the 1960s. Another person, Louis Dooley, has also claimed to have coined the term at MIT Lincoln Laboratory around 1956 or 1957.
A byte per second is eight bits per second, the smallest rate counted in bytes. Protocol documents that need to avoid any ambiguity often use the word octet for exactly eight bits. The unit is tiny by modern standards. On serial links, start, stop and parity bits mean the line must run at a higher bit rate than the byte rate alone suggests.
1 byte per second = 8 bits per second (exactly).

Mebibyte Per Second (MiB/s)
1,048,576 bytes per second (8.39 Mbps). Used by some operating systems and storage tools.
Mebibyte is one of the newest words in computing. In December 1998 the IEC approved names for binary multiples, published in 1999 as an amendment to IEC 60027-2. Each keeps the first two letters of its SI counterpart and adds bi for binary, so mebi stands for 2²⁰. The aim was to stop mega meaning 10⁶ in telecommunications and storage but 2²⁰ in memory, a split that left room for incompatibility.
A mebibyte per second is 1,048,576 bytes per second, about 8.39 Mbit/s, so it is roughly 4.9 percent larger than 1 MB/s. Some operating systems and tools divide by 1,024 and then print the result with a plain MB label, so one program may show 11.9 for a transfer that another shows as 12.5. For example, a 100 Mbit/s link carries about 11.92 MiB/s at most. The IEEE chose to keep SI meanings in its own standards, allowing base-two use of mega only when explicitly noted.
1 mebibyte per second = 8,388,608 bits per second (exactly).
