Speed & transfer
MB/s to Mbps Converter
Convert megabytes per second (MB/s) to megabits per second (Mbps).
How do you convert MB/s to Mbps?
Multiply megabytes per second by 8. This is the conversion to use when a download window shows a speed in MB/s and you want to compare it with the Mbps figure on your internet plan.
Formula
Mbps = MB/s × 8
Example
A file copy running at 12.5 MB/s is moving 100 Mbps. If your plan is 100 Mbps, you are getting the full speed. A copy at 5 MB/s equals 40 Mbps – less than half of that plan.
When to use it
Use it to check whether a slow transfer is limited by your connection or by something else, such as a slow USB drive, a busy server or Wi-Fi.
FAQ
Frequently asked questions about the MB/s to Mbps Converter
Why multiply by 8?
There are 8 bits in one byte, so a value in bytes always represents 8 times as many bits.
What is 50 MB/s in Mbps?
50 MB/s × 8 = 400 Mbps.
Is lowercase b different from uppercase B?
Yes. Lowercase b means bits and uppercase B means bytes. Mbps is megabits per second; MB/s is megabytes per second.
