About the Megabits to Megabytes per Second
The Megabits to Megabytes per Second calculator converts internet speeds in megabits per second (Mbps) into megabytes per second (MB/s). It helps you compare a connection's advertised bit rate with the byte-based transfer rates often shown by download software. With the default input of 1 Mbps, the result is 0.125 MB/s.
- Value in Mbps (Mbps)
- Enter the internet or data-transfer speed in megabits per second (Mbps); the default value is 1.
Formula and method
R_MB = R_Mb / 8; equivalently, R_Mb = 8 × R_MB.
- R_MBData-transfer rate in megabytes per second (MB/s), the converted output.
- R_MbData-transfer rate in megabits per second (Mbps), the input.
Divide the entered Mbps value by 8 because one byte contains eight bits. Both units use the same decimal mega prefix, so no additional scaling is needed. For the default input, 1 ÷ 8 = 0.125 MB/s.

How to use the Megabits to Megabytes per Second
- 1Find the connection speed you want to convert and confirm that it is expressed in Mbps.
- 2Enter it in Value in Mbps (Mbps), or leave the default value of 1.
- 3Read the MB/s result, calculated by dividing the input by 8.
- 4Check the forward conversion row: with the default input, 1 Mbps = 0.125 MB/s.
- 5Use the reverse reference row, 1 MB/s = 8 Mbps, to confirm the relationship between the units.
Reading your result
The result row, MB/s = 0.125, gives the converted transfer rate for the default input. The forward row, shown as '1 Mbps = = 0.125 MB/s', states the same equivalence; the repeated equals sign is only display formatting. The reverse row, shown as '1 MB/s = = 8 Mbps', is a unit reference rather than a second result for your input.
Limitations
This is a unit conversion, not a speed test or a guarantee of download performance. It assumes decimal units: a megabit is 1,000,000 bits and a megabyte is 1,000,000 bytes. Actual file-transfer rates can be lower because of protocol overhead, network congestion, Wi-Fi conditions, and server or storage limits. MB/s is not the same as MiB/s, which uses binary mebibytes. Use nonnegative speed values; negative rates do not represent ordinary download or upload speeds.
Common questions
Why does the calculator divide Mbps by 8?+
Mbps counts bits, while MB/s counts bytes. Since each byte contains eight bits, the same transfer rate has a byte-based value one-eighth as large: 1 Mbps = 0.125 MB/s.
Does the capital B in MB/s matter?+
Yes. Lowercase b means bits, while uppercase B means bytes. Mbps means megabits per second, whereas MB/s means megabytes per second.
Will a 1 Mbps connection download files at exactly 0.125 MB/s?+
Not necessarily. 0.125 MB/s is the exact unit conversion of 1 Mbps, but usable file-download throughput may be lower because some capacity carries protocol data and because network or device conditions can limit performance.
Can I compare this result directly with a download rate in MiB/s?+
No. This calculator outputs decimal MB/s, not binary MiB/s. A megabyte contains 1,000,000 bytes, while a mebibyte contains 1,048,576 bytes, so the numerical rates differ.
Does the calculator save my information?+
Calculations run in your browser. While signed in, inputs and results are automatically recorded in account history; saving a result creates a separate saved record.
