Convert Megabits per second (Mbps) to Megabytes per second (MB/s)
1 Mbps = 0.125 MB/s Two-way converter below, type in either field.
Formula
MB/s = Mbps ÷ 8
Why this matters
One byte is 8 bits, so line speed in megabits per second divided by 8 gives file-transfer speed in megabytes per second. A 100 Mbps plan tops out at 12.5 MB/s in a download manager, that is the same speed in different units, not a slow connection.
Mbps to MB/s reference table
| Megabits per second (Mbps) | Megabytes per second (MB/s) |
|---|---|
| 5 | 0.625 |
| 10 | 1.25 |
| 25 | 3.125 |
| 50 | 6.25 |
| 100 | 12.5 |
| 200 | 25 |
| 300 | 37.5 |
| 500 | 62.5 |
| 1,000 | 125 |
Frequently asked questions
Why does my 100 Mbps internet only download at 12 MB/s?
Because 100 megaBITS per second is 12.5 megaBYTES per second (divide by 8). Seeing ~11–12 MB/s means your line is performing normally after protocol overhead.
Is Mbps or MB/s bigger?
MB/s is the bigger unit: 1 MB/s = 8 Mbps. ISPs advertise in Mbps partly because the number is 8× larger.
What speed do I need to stream 4K?
Netflix recommends 15–25 Mbps (about 2–3 MB/s) per 4K stream. Most congestion problems come from sharing that across devices, not the stream itself.
