Conversion method
Bits per second and bytes per second differ by eight. Decimal prefixes are used here; Mbps is not MB/s.
MB/s = x × 0.125
10 Mbit/s = 1.25 MB/s.
| Mbit/s | MB/s |
|---|---|
| 1 | 0.125 |
| 5 | 0.625 |
| 10 | 1.25 |
| 25 | 3.125 |
| 50 | 6.25 |
| 100 | 12.5 |

Precision of data transfer rate conversions
All 26 data transfer rate units convert through Bit per second (bit/s). 26 have an exact defined relationship to the base unit and 0 are conventional or measured values. Results and the tables on this page come from the same engine, so a table value can be checked against the converter directly.
Standard display shows up to six decimal places, switching to scientific notation for very large or small values. Calculation uses JavaScript binary floating point independently of display rounding, so extra digits are not a claim about measurement accuracy. Each unit lists its own source; a citation records where the definition comes from, not an independent review. See Conversion methodology for the review and correction process.
