In short
How many MB/s is 400 Mbps?

The working
The factor below is an exact definition rather than a measurement, so nothing is approximated in the arithmetic. The only rounding on this page happens where a number is displayed.
1 Mbp = 0.125000 MB/s 400 × 0.125000 = 50.000
How much precision do you need?
Each row is the same answer cut at a different number of decimals, with what that choice costs you. Pick the shortest row whose error is smaller than whatever you are measuring with.
| Rounded to | Answer (MB/s) | Off by |
|---|---|---|
| Whole number | 50 | exact |
| 1 decimal | 50.0 | exact |
| 2 decimals | 50.00 | exact |
Round trip: take 50.000 MB/s back the other way and you land on 400.0000 Mbps — a drift of 0.0000 Mbps. That gap is the rounding, not the conversion.
