Plotly Graph
This chart compares the current speed across common units.
Example Data Table
| Input Speed | From Unit | To Unit | Converted Result | Example Use |
|---|---|---|---|---|
| 100 | Mbps | MB/s | 12.5 MB/s | Estimate download tools and storage write needs. |
| 1 | Gbps | Mbps | 1000 Mbps | Compare internet plans and switch uplinks. |
| 500 | MB/s | Gbps | 4 Gbps | Check fast server replication capacity. |
| 250 | Mibps | MiB/s | 31.25 MiB/s | Review binary throughput inside system tools. |
| 10 | Gbps | GiB/s | 1.1642 GiB/s | Plan backbone links and storage ingestion. |
Formula Used
Core conversion formula:
Converted Speed = Input Speed × From Unit Factor ÷ To Unit Factor
Effective throughput formula:
Effective bps = Raw bps × (Efficiency ÷ 100) × (1 − Overhead ÷ 100)
Transfer time formula:
Transfer Time = File Size in Bits ÷ Effective bps
Data moved during a duration:
Transferable Data = Effective Bytes Per Second × Selected Duration
Decimal units use powers of 1000. Binary units use powers of 1024. Byte-based units multiply bit rates by eight during conversion.

FAQs
1. Why do Mbps and MB/s produce different numbers?
Mbps means megabits per second. MB/s means megabytes per second. One byte equals eight bits, so MB/s values are smaller when starting from the same bit rate.
2. What is the difference between decimal and binary units?
Decimal units use 1000-based steps, like Mbps and GB. Binary units use 1024-based steps, like Mibps and GiB. Storage tools often display binary values.
3. Why is effective speed lower than converted speed?
Effective speed applies your efficiency and overhead settings. This produces a more realistic throughput estimate for actual traffic, protocol handling, and application limits.
4. Can I use this for internet plans?
Yes. It helps compare plan advertisements, router limits, and expected file transfer rates. Use realistic efficiency and overhead values for closer real-world estimates.
5. Does this tool estimate download time?
Yes. Enter a file size and the calculator estimates transfer time from the effective throughput. Larger overhead or lower efficiency will increase the estimate.
6. What efficiency value should I use?
For many practical cases, values between 85% and 98% work well. Lower values reflect congestion, hardware limits, wireless losses, or application overhead.
7. Can this calculator help with storage networking?
Yes. Convert link rates into bytes per second, compare file movement speeds, and estimate how much data storage systems can ingest during set windows.
8. Why do some systems show MiB/s instead of MB/s?
Many operating systems and monitoring tools prefer binary units. MiB/s is based on 1024-byte steps, while MB/s uses 1000-byte steps, so displayed numbers differ.
