How it works
Internet speeds are quoted in megabits per second (Mbps), while file sizes use megabytes (MB). One byte has 8 bits, so divide Mbps by 8 to get MB/s — a 100 Mbps connection downloads at most 12.5 MB/s.
Formula
MB/s = Mbps / 8
Worked examples
- 300 Mbit/s = 37.5 MB/s
- 1,000 Mbit/s = 125 MB/s

Frequently asked questions
How fast is 100 Mbps in MB/s?
100 Mbps ÷ 8 = 12.5 MB/s at most; in practice usually 11–12 MB/s.
What is the difference between Mb and MB?
A lowercase b means bits, an uppercase B means bytes. One byte has 8 bits.
