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 are two different units measuring the same physical quantity. A megabit per second is defined as exactly 0.125 MB/s, and a megabyte per second as exactly 8 Mbps. Because the units differ in size, the number you write down for the same amount depends on which unit you use - the conversion factor itself is exact, with no rounding.
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.
