Common plan speeds in MB/s
The last column applies the roughly 95% ceiling that TCP/IP overhead leaves on a typical connection, so it is closer to the best number you will see in a download manager.
| Plan | MB/s (pure conversion) | About what downloads show at best |
|---|---|---|
| 25 Mbps | 3.1 MB/s | 3.0 MB/s |
| 100 Mbps | 12.5 MB/s | 11.9 MB/s |
| 300 Mbps | 37.5 MB/s | 35.6 MB/s |
| 500 Mbps | 62.5 MB/s | 59.4 MB/s |
| 1 Gbps | 125 MB/s | 118.8 MB/s |
Where you will see each unit
- Mbps / Gbps: internet plans, speed tests, router status pages, Wi-Fi link rates.
- MB/s: Steam, the Epic Games launcher, browser download lists and most file-copy windows. Some apps let you switch Steam to bits in its download settings.
- Kbps: slow or throttled connections (for example mobile data after a cap), audio bitrates and call requirements. Zoom, for instance, lists 60–80 Kbps for audio-only calls.
Capital letters matter
A lowercase b means bits and an uppercase B means bytes. "Mb" and "MB" are different units, and a missing slash ("MBps") is easy to misread. When a number seems eight times too low, check the letter first.
