Mbps vs MBps

Mbps vs MBps is the difference between megabits per second and megabytes per second. A byte holds 8 bits, so a speed in megabytes is one eighth of the same speed in megabits.

Why it matters

Internet plans and network links are sold in megabits per second, while download progress bars and file sizes usually show megabytes. Mixing them up leads to unrealistic expectations of how fast a download should be.

The lowercase b stands for bit and the uppercase B for byte.

Example

100 Mbps / 8 = 12.5 MBps

A 1 GB (1000 MB) file at 12.5 MBps:
1000 / 12.5 = 80 seconds, best case

Real transfers take longer because of protocol overhead, congestion and server limits.

Common mistakes

• Expecting a 100 Mbps connection to download at 100 MB per second.
• Writing Mb when you mean MB in specs and documentation.
• Forgetting overhead, so the practical rate is lower than the line rate.
