Calculating speed and time
Divide Mbps by eight to obtain decimal MB/s. For a 100 GB file at 100 Mbps and 80% efficiency: 100 × 1000 ÷ 10 = 10,000 seconds, or 2 h 46 min 40 s.
| Item | Value |
|---|---|
| 100 Mbps | 12.5 MB/s |
| 300 Mbps | 37.5 MB/s |
| 1,000 Mbps | 125 MB/s |
Calculated examples; rounded values.
Why actual speed can be lower
Overhead, the source server, storage and the local network can limit throughput. The 80% figure is an editable assumption, not a guarantee or measurement. MiB/s is a different unit from MB/s.
Frequently asked questions
Does a 1000 Mbps connection download at 1000 MB/s?
No. Its theoretical decimal maximum is 125 MB/s before overhead and other constraints. An actual measurement may be lower.
