Most data transfer rate units step by powers of ten: moving up the scale (bps → Kbps → Mbps → Gbps and beyond) means multiply by 1000, moving down means divide by 1000 — usually just a matter of shifting the decimal point. What's actually being counted underneath is bits: the binary digits, 0s and 1s, that make up every network signal.

SI Decimal vs Binary: Why MB/s to KiB/s Is Not a Round Number
Megabyte Per Second (MB/s) is an SI decimal unit: each prefix step multiplies by 1,000, so 1 MB/s = 8,000,000 bps. Kibibyte Per Second (KiB/s) is an IEC binary unit: each prefix step multiplies by 1,024, so 1 KiB/s = 8,192 bps. Dividing one by the other gives 976.5625, which is why MB/s to KiB/s is not a round number.
| Unit | Standard | Prefix step | 1 unit equals |
|---|---|---|---|
| Megabyte Per Second (MB/s) | SI decimal | 1,000 | 8,000,000 bps |
| Kibibyte Per Second (KiB/s) | Binary (IEC) | 1,024 | 8,192 bps |
To compare like with like, use MB/s to KB/s for SI decimal or MiB/s to KiB/s for binary (IEC).

-
How do I convert megabytes per second to kibibytes per second?
MB/s × 976.5625 = KiB/s
Multiply the megabyte per second value by 976.5625 to get kibibytes per second. For example, 10 MB/s = 9,765.625 KiB/s. To convert back (vice versa), multiply kibibytes per second by 0.001024.
-
Is megabyte per second bigger than kibibyte per second?
MB/s is 976.5625× larger than KiB/s
Yes. 1 MB/s = 976.5625 KiB/s, so megabyte per second is the larger transfer rate unit.
-
Why is MB/s to KiB/s not a round number?
1 MB/s = 8,000,000 bps · 1 KiB/s = 8,192 bps
Megabyte Per Second (MB/s) is an SI decimal (base 10) unit and Kibibyte Per Second (KiB/s) is a binary IEC (base 2) unit, so their prefixes step by 1,000 and 1,024. That is why 1 MB/s = 976.5625 KiB/s instead of a round number.
-
What is Megabyte Per Second (MB/s) commonly used for?
Common uses of the megabyte per second (MB/s) include: SSD benchmarks, USB transfer speeds, network file copies, download managers.
