Megabits per Second vs Megabytes per Second
Compare megabits per second and megabytes per second side by side, convert in both directions, and see the exact factor - Data Transfer Rate units.
= 0.125 MB/s
= 8 Mbps
1 megabit per second = 0.125 MB/s · 1 megabyte per second = 8 Mbps
The Megabits per Second is the smaller unit - the same amount has a smaller number when measured in it.
| Megabits per Second (Mbps) | Megabytes per Second (MB/s) | Megabytes per Second (MB/s) | Megabits per Second (Mbps) |
|---|---|---|---|
| 1 | 0.125 | 1 | 8 |
| 2 | 0.25 | 2 | 16 |
| 5 | 0.625 | 5 | 40 |
| 10 | 1.25 | 10 | 80 |
| 25 | 3.125 | 25 | 200 |
| 50 | 6.25 | 50 | 400 |
| 100 | 12.5 | 100 | 800 |
| 250 | 31.25 | 250 | 2,000 |
| 500 | 62.5 | 500 | 4,000 |
| 1000 | 125 | 1000 | 8,000 |
Quick Answer
1 megabit per second (Mbps) = 0.125 megabytes per second (MB/s), and 1 megabyte per second = 8 megabits per second. Megabytes per Second is the larger unit, so the same physical amount needs a bigger number when measured in megabits per second. Convert either way with the live tool below or the dedicated converter pages.
Key Facts
- 1 megabit per second (Mbps) = 0.125 MB/s
- 1 megabyte per second (MB/s) = 8 Mbps
- Conversion is exact multiplication - no rounding in the factor
- Table below covers common values in both directions
- Dedicated converters: Mbps→MB/s and MB/s→Mbps pages with live tools
Frequently Asked Questions
Which is bigger, a megabit per second or a megabyte per second?
One megabit per second equals 0.125 MB/s, and one megabyte per second equals 8 Mbps. The unit with the larger factor is the physically bigger one.
How do I convert megabits per second to megabytes per second?
Multiply by the factor: value in MB/s = value in Mbps × 0.125. Example: 5 Mbps = 0.625 MB/s. Reverse: divide by 0.125 (or multiply by 8).
Why are megabits per second and megabytes per second different?
They come from different measurement systems - Megabits per Second belongs to the metric (SI) world, Megabytes per Second to the US customary world (or another convention). The conversion is exact: 0.125 MB/s per megabit per second, no rounding needed for the factor itself.
Is there a quick way to convert without a calculator?
Memorize the 1-to factor: 1 megabit per second ≈ 0.125 MB/s. Then multiply. For 2 Mbps that's ≈ 0.25 MB/s.
