Mbps to MB/s Converter: Internet to File Speed
Start with the Mbps number from an internet plan or speed test. The converter returns the matching file-transfer rate in MB/s—the unit commonly shown by browsers, launchers, and download apps.
Divide any Mbps value by 8. For example, 10 Mbps is 1.25 MB/s and 100 Mbps is 12.5 MB/s before real-world overhead.

Transparent math, not a mystery result.
NetCalcKit uses standard decimal network units unless the page explicitly says otherwise. The calculator updates in your browser and labels ideal estimates separately from real-world conditions.
Quick reference
Mbps to MB/s conversion table
The MB/s column is the ideal file-transfer rate: divide Mbps by eight. MB per minute and GB per hour assume the connection sustains that rate continuously and use decimal units.
| Internet speed | File speed | Per minute | Per hour |
|---|---|---|---|
| 1 Mbps | 0.125 MB/s | 7.5 MB | 0.45 GB |
| 5 Mbps | 0.625 MB/s | 37.5 MB | 2.25 GB |
| 10 Mbps | 1.25 MB/s | 75 MB | 4.5 GB |
| 20 Mbps | 2.5 MB/s | 150 MB | 9 GB |
| 50 Mbps | 6.25 MB/s | 375 MB | 22.5 GB |
| 100 Mbps | 12.5 MB/s | 750 MB | 45 GB |
| 500 Mbps | 62.5 MB/s | 3,750 MB | 225 GB |
| 1000 Mbps | 125 MB/s | 7,500 MB | 450 GB |
Units made simple
Mbps and MB/s are different measurements
Internet providers normally advertise megabits per second, written Mbps with a lowercase b. Browsers, game launchers, and file managers often show megabytes per second, written MB/s with an uppercase B.
A byte contains eight bits. That is why the same connection has a smaller-looking number in MB/s: 80 Mbps and 10 MB/s describe the same ideal rate. The unit label matters more than the size of the number.
- Mbps = megabits per second, commonly used for network and internet speeds.
- MB/s = megabytes per second, commonly used for files and downloads.
- Convert Mbps to MB/s by dividing by 8.
- A query such as “1 Mbps to MB” needs a duration: at 1 Mbps, the ideal rate is 0.125 MB each second, 7.5 MB each minute, or 0.45 GB each hour.
Put it to work
Four real-life conversion examples
These examples use decimal file sizes and the ideal converted rate. Treat the time as a baseline, then allow extra room when the connection or server cannot sustain the headline speed.
1 Mbps mobile link
0.125 MB/sA 100 MB file has an ideal transfer time of about 13 minutes 20 seconds.
10 Mbps connection
1.25 MB/sA 1 GB download has an ideal transfer time of about 13 minutes 20 seconds.
100 Mbps home internet
12.5 MB/sA 5 GB game update has an ideal transfer time of about 6 minutes 40 seconds.
1000 Mbps gigabit plan
125 MB/sA 100 GB transfer has an ideal time of about 13 minutes 20 seconds if every part of the path can keep up.
Check the comparison
Common Mbps-to-MB/s mistakes
Most wrong answers come from mixing a rate, a file size, and a time period. Keep the slash in MB/s visible and write the unit beside every number while calculating.
- Reading the lowercase b in Mbps as an uppercase B and assuming 100 Mbps means 100 MB/s.
- Multiplying Mbps by eight instead of dividing when converting to MB/s.
- Comparing an advertised maximum with one short real-world download and treating the difference as a formula error.
- Mixing decimal MB and GB with binary MiB and GiB without checking which convention an app uses.
- Converting Mbps directly to MB or GB without specifying seconds, minutes, hours, or another duration.

Common questions
Good to know.
Is 1 Mbps the same as 1 MB/s?+
No. One byte contains eight bits, so 1 Mbps equals 0.125 MB/s. A connection needs 8 Mbps to move an ideal 1 MB each second.
What is 10 Mbps in MB/s?+
10 Mbps divided by eight is 1.25 MB/s. At that ideal rate, one decimal gigabyte takes about 13 minutes 20 seconds to transfer.
Should I multiply or divide Mbps to get MB/s?+
Divide the Mbps value by eight. For example, 40 Mbps becomes an ideal file-transfer rate of 5 MB/s.
Why is my download slower than the converted MB/s?+
The conversion is an ideal ceiling. Wi-Fi, protocol overhead, server limits, congestion, storage speed, and other devices can lower sustained file speed.
Is 1000 Mbps equal to 125 MB/s?+
Yes, mathematically: 1000 ÷ 8 = 125 MB/s. A real gigabit connection often delivers less because the whole transfer path must keep up.
