Gbps → MB/s (Fast Guide)
Core Idea: 1 Gbps = 125 MB/s. Multiply by 125 to convert gigabits per second to megabytes per second.
Formula
MB/s = Gbps × 125
Quick Values
- 0.5 Gbps → 62.5 MB/s
- 1 Gbps → 125 MB/s
- 2.5 Gbps → 312.5 MB/s
- 5 Gbps → 625 MB/s
- 10 Gbps → 1250 MB/s
3‑Step Example (2.5 Gbps)
- 2.5 × 125
- = 312.5
- Units: MB/s
Uses
- Download manager speeds
- Media / NAS workflows
- Cloud backups & sync
- Game + OS updates
Accuracy & Tips
- Real 1 Gbps ≈ 110–118 MB/s
- Need SSD/NVMe for multi‑gig
- Wired beats Wi‑Fi for sustained rate
Examples
- 1.2 Gbps → 150 MB/s
- 3 Gbps → 375 MB/s
- 8 Gbps → 1000 MB/s
FAQ
Why 125? (1000 ÷ 8) = 125.
Not seeing full speed? Overhead + server/device limits.
Need >1 Gbps? Large media / multi-user throughput.
Tip: For GB/s just divide MB/s by 1000 (1250 MB/s ≈ 1.25 GB/s).
