Convert megabits per second to megabytes per second in one step. Type a value, change the units if you need a different pair, and the answer updates as you type, with the reverse rate and a quick reference list.
Results are estimates for planning. Check the figures before you make a financial or health decision.
How to convert megabits per second to megabytes per second
Multiply the number of Mbps by 0.125 to get MB/s:
MB/s = Mbps × 0.125
To go the other way, divide by 0.125 (or multiply by 8). The converter stores each unit as a multiple of a base unit, so you can also pick any other pair of units from the same group.
Worked example
Using the default values in the converter above:
| Input | Value |
|---|---|
| Value | 100 |
| From | Megabits per second |
| To | Megabytes per second |
100 megabits per second equals 12.5 megabytes per second
Mbps to MB/s reference table
| Megabits per second | Megabytes per second |
|---|---|
| 1 Mbps | 0.125 MB/s |
| 10 Mbps | 1.25 MB/s |
| 50 Mbps | 6.25 MB/s |
| 100 Mbps | 12.5 MB/s |
| 200 Mbps | 25 MB/s |
| 500 Mbps | 62.5 MB/s |
| 1,000 Mbps | 125 MB/s |
| 2,000 Mbps | 250 MB/s |
| 5,000 Mbps | 625 MB/s |
Tips and common mistakes
Internet speeds are advertised in megabits per second (Mbps), but downloads usually show in megabytes per second (MB/s). Because a byte is 8 bits, divide Mbps by 8 to get MB/s: a 100 Mbps connection tops out at 12.5 MB/s.
Real speeds are usually lower than the advertised figure because of Wi-Fi quality, network congestion, protocol overhead and the speed of the server you are downloading from. Treat the result as the theoretical maximum.
Watch the capital letters: Mb or Mbps (megabits) is not the same as MB or MB/s (megabytes).
Frequently asked questions
How many megabytes per second are in 1 Mbps?
1 Mbps equals 0.125 megabytes per second.
How do I convert Mbps to MB/s by hand?
Multiply the Mbps figure by 0.125. For example, 100 Mbps × 0.125 = 12.5 MB/s.
How do I convert MB/s back to Mbps?
Divide the MB/s figure by 0.125, or multiply it by 8. For example, 12.5 MB/s is 100 Mbps.
Why is my download slower than the advertised speed?
Advertised speeds are theoretical maximums. Wi-Fi quality, congestion, overhead and the server you download from all reduce what you actually see.
