About this tool: Data Transfer Time
Estimate file transfer time from size, speed and efficiency. Network overhead depends on efficiency.
Mbps measures megabits per second, whereas MB/s measures megabytes per second: one byte is eight bits. Decimal MB and GB differ from binary MiB and GiB. Efficiency lowers usable throughput to account for overhead; the result is an estimate rather than a network speed test.
How the calculation works
Worked example
| File size | 1 |
| Size unit | GB (10⁹ B) |
| Speed | 100 |
| Speed unit | Mbps |
| Efficiency, % | 100 |
1 GB; 100 Mbps; 100% → 80 s

What affects precision and input format?
Floating-point results are rounded for display. Keep the units shown in the input labels; decimal points and decimal commas are accepted.
Where are the calculations performed?
The calculation runs in your browser. You can use the tool without installing software.
