How to convert data transfer rate
Internet plans are sold in megabits per second (Mbit/s), while downloads and disks are usually shown in megabytes per second (MB/s). There are 8 bits in a byte, so a 100 Mbit/s connection moves at most 12.5 MB/s.
Every data transfer rate unit is a fixed multiple of one base unit, the bit/s. To convert a value, multiply it by the size of the starting unit and divide by the size of the target unit. For example, to convert Mbit/s to MB/s, multiply by 0.125. To go the other way, divide by 0.125.
The converter above does this for you and shows the exact formula under the result.

Frequently asked questions
How many MB/s is 100 Mbit/s?
100 Mbit/s is 12.5 MB/s, because you divide megabits by 8 to get megabytes.
How long does a download take?
Divide the file size by the speed in the same units. A 1 GB file at 100 Mbit/s (12.5 MB/s) takes about 80 seconds in ideal conditions; real speeds are usually lower.
How do I convert Mbit/s to MB/s?
Multiply the value in Mbit/s by 0.125 to get MB/s. For example, 10 Mbit/s = 1.25 MB/s.
How many MB/s is 1 Mbit/s?
1 Mbit/s = 0.125 MB/s, and 1 MB/s = 8 Mbit/s.
