Mbps to mb/s converter

Use this converter to easily convert between MegaBits per second and MegaBytes per second (Mbps to MB per sec.).

Quick navigation:

How many MegaBits per second equal 1 MegaByte per second?

Using the binary definition of the megabyte (MB), 8.192 megabits per second (mbps) equal 1 megabyte per second (MB/s). Using the SI (International System of Units) standard of the megabyte, 8,000 megabits per second equal one megabyte per second. You are not the only one confused here, continue reading to understand why.

Both of the above answers are correct, depending on the unit convention that is relevant (agreed on) in your particular case. First, we have the binary system in which units are powers of 2, e.g. 1 MB is 210 KB = 1024 KB. From this definition it follows that one megabyte is 8,388,608 bits. Then, we have the decimal SI convention, according to which one MB = 103 KB = 1,000 KB, so one megabyte is 8,000,000 bits. As you can imagine, having the same name for a unit with two different definitions is not a great situation. When using our mbps to MB converter, one can easily use both units.

Difference between Mbps and MB/s

A MB per second (MB/s) is a non-standard unit for network throughput, often used due to its convenience since most file sizes one works with are in usually expressed in byte-units: KB, MB, GB, etc., and not bit-units like kbps and mbps. A MB can be defined in the binary and the decimal convention, as described above. On the other hand, a MegaBit per Second (mbps) is a standard bandwidth measurement metric for network equipment, such as routers, switches and LAN cards, and is equal to 1,000,000 bits per second, or 1,000 kilobits per second.

In practice, mbps is the unit in which your optic, broadband, LAN or DSL connection will be advertised in. You likely see prices internet connection speeds advertised as 25 mbps, 50 mbps, 75 mbps, or 32 mbps, 48 mbps, 64 mbps, etc. Business connections may go up to 300 mbps, and more. You most likely have a 100 mbit LAN card on your PC or MAC, therefore it has a maximum transfer rate of 100 mpbs. Currently the fastest available LAN cards go up to 160 gbps.

How to convert Mbps to MB per second

The easiest way to convert mbps to MB/s is through our converter. However, if you want a step by step solution, then it is easiest to first convert each metric to bit-level metrics, then convert back to the desired unit.

For example, 25 mbps is equal to 25 x 1,000,000 bps. To convert to Bytes, divide by 8 (1 Byte = 8 bits): 25,000,000 / 8 = 3,125,000 Bytes. In the SI standard, that converts to 3,125,000 / 1,000,000 = 3.125 MB/s, while in the binary convention it converts to 3,125,000 / 1,048,576 = 3.0518 MB/s. More examples using a simplified procedure below.

Mbps to MB per second conversion example

Sample task: convert 100 Mbps to MB/s (binary, also MiB/s). Solution:

Formula:
Mbps / 8.388608 = MBps
Calculation:
100 Mbps / 8.3886 = 11.920929 MBps
End result:
100 Mbps is equal to 11.920929 MBps

Sample task: convert 100 Mbps to MB/s (SI). Solution:

Formula:
Mbps / 8 = MBps
Calculation:
100 Mbps / 8 = 12.50 MBps
End result:
100 Mbps is equal to 12.50 MBps
