Result: 12.500000A lowercase b is a bit, an uppercase B is a byte, and a byte holds eight bits. That single letter is a factor of 8: a 100 Mbit/s line tops out at 12.5 MB/s. Every prefix here is decimal, so 1 Gbit/s is exactly 1000 Mbit/s.

Questions
Why does a 100 Mbit/s line only download at 12.5 MB/s?
Because one byte is 8 bits. Plans are sold in megabits per second, while browsers and file managers report megabytes per second, so you divide by 8: 100 ÷ 8 = 12.5. It is not a fault, it is the units.
What is the difference between Mbit/s and MB/s?
Mbit/s is megabits per second and MB/s is megabytes per second, and a byte holds 8 bits. So 1 MB/s equals 8 Mbit/s. The lowercase b means bit and the uppercase B means byte — one small letter, an eightfold difference.
Does this converter use 1000 or 1024 per step?
1000, the convention for network speeds: 1 kbit/s is 1000 bit/s and 1 Gbit/s is exactly 1000 Mbit/s. The 1024-based units belong to storage sizes, not to rates.
Where are these units actually used?
Broadband and Wi-Fi are advertised in Mbit/s or Gbit/s, download managers and cloud sync show MB/s, and streaming bitrates are quoted in Mbit/s. Converting tells you whether a 50 Mbit/s stream fits a 10 MB/s line — it does, because 10 MB/s is 80 Mbit/s.
