Mbps → MB/s (Quick Conversion)
Core Idea: Divide megabits per second by 8 to get megabytes per second.
Formula
MB/s = Mbps ÷ 8
Quick Values
- 8 Mbps → 1 MB/s
- 50 Mbps → 6.25 MB/s
- 100 Mbps → 12.5 MB/s
- 300 Mbps → 37.5 MB/s
- 1000 Mbps → 125 MB/s
3‑Step Example (150 Mbps)
- 150 ÷ 8
- = 18.75
- Units: MB/s
Uses
- Download time estimates
- Streaming bitrate checks
- Comparing ISP plan claims vs actual
Accuracy & Tips
- Bits (b) vs Bytes (B): 8 bits = 1 byte
- Displayed download speeds usually MB/s
- Binary (MiB) matters for storage, not line rate
Examples
- 25 Mbps → 3.125 MB/s
- 420 Mbps → 52.5 MB/s
- 940 Mbps → 117.5 MB/s
FAQ
Why does my download look slower? It’s MB/s not Mbps. 1 Gbps? 125 MB/s. Shortcut? Divide by 8 (halve three times).
Mental shortcut: /8 = ÷2 ÷2 ÷2 (e.g. 200 → 100 → 50 → 25 MB/s).
