Mbps to MB/s converter
Convert a connection speed from megabits per second (Mbps) — how internet speeds are advertised — to megabytes per second (MB/s) — how download progress and file sizes are usually shown.

Speed
How to use this calculator
- Enter a speed in Mbps.
- Read the equivalent in MB/s.
Assumptions
- A direct unit conversion — real download speeds are usually somewhat below the theoretical maximum due to network overhead.
Technical details: what the fields mean
- Speed
mbps - Connection speed in megabits per second, as advertised by an ISP or shown in a speed test.
Methodology
MB/s = Mbps ÷ 8, since 1 byte = 8 bits.
Worked example
100Mbps connection
Inputs: mbps=100
Result: 12.50 MB/s
Practical guidance
- Use this to sanity-check a download progress bar against your advertised connection speed — they're often confused because one uses bits and the other bytes.
Common mistakes
- Assuming a '100Mbps' connection downloads at 100MB/s — it's actually 12.5MB/s, since Mbps counts bits, not bytes.
FAQs
Is Mbps the same as MB/s?
No — Mbps is megabits per second, MB/s is megabytes per second. Divide Mbps by 8 to get MB/s.
