How to use this calculator
- Enter your speed in Mbps.
- Press Calculate.
How it works
Internet speed is in megabits (Mbps) but files are in megabytes (MB). Divide Mbps by 8 to get MB/s.
Worked example
80 Mbps. = 10 MB/s.
Common mistakes
- Confusing Mbps (megabits) with MB/s (megabytes) — they differ by a factor of 8.
- Forgetting that lowercase b means bits and uppercase B means bytes.
Frequently asked questions
How do I convert Mbps to MB/s?
Divide by 8: 100 Mbps is 12.5 MB/s, because there are 8 bits in a byte.
Why do ISPs advertise in megabits?
Network speeds are measured in bits per second, so the megabit figure looks larger; file sizes are in bytes, which is why downloads feel slower than the number suggests.
Why divide by 8?
There are 8 bits in a byte. Speeds are sold in megabits (Mbps) but files are measured in megabytes (MB), so an 80 Mbps line downloads at about 10 MB/s.
