Data Transfer Rate Converter – All Bandwidth Units in One Tool
Convert between Kbps, Mbps, Gbps, Tbps, and byte-per-second units instantly. Ideal for planning capacity, decoding ISP claims, and estimating transfer times.
1. Core Relations
- 1 Kbps = 1000 bps
- 1 Mbps = 1000 Kbps = 1,000,000 bps
- 1 Gbps = 1000 Mbps
- 1 MB/s = 8 Mbps
- 1 GB/s = 8 Gbps
2. Quick Examples
- 25 Mbps = 0.025 Gbps
- 100 Mbps = 12.5 MB/s
- 1 Gbps = 125 MB/s
- 500 Kbps = 0.5 Mbps
- 2 Gbps = 2000 Mbps
- 10 MB/s = 80 Mbps
3. How to Convert
- Choose source & target units above.
- Tool converts via base bps.
- Use result for sizing / time estimates.
- Adjust decimals for clarity (engineering vs marketing).
4. Common Use Cases
SLA audits, streaming capacity planning, data migration timing, multi‑site WAN design, cloud egress budgeting.
5. Accuracy & Caveats
- Marketing speeds ignore protocol overhead (expect 85–95%).
- Wi‑Fi real throughput < stated PHY rate.
- Latency doesn’t reduce peak rate but affects transfers with many round trips.
- For large files: time (s) ≈ (size_MB × 8) ÷ Mbps.
6. Worked Examples
100 Mbps line → 100 × 0.125 = 12.5 MB/s practical max.
4 GB file @ 200 Mbps: size_MB=4096 → time ≈ (4096×8)/200 = 163.84 s (~2m 44s).
750 MB backup over 25 Mbps: (750×8)/25 = 240 s (4 min).
7. Quick FAQ
Why bits for network & bytes for files? Historical telecom vs storage conventions.
Binary ever used here? Line rates use decimal (×1000).
Why is speed lower than advertised? Protocol overhead + contention.
8. Action Tip
Run a conversion above—chain to MB/s, then estimate transfer time with the examples formula.
