Internet Speed Conversion FAQ
Everything you need to know about the difference between megabits and megabytes per second.
Mbps stands for megabits per second and is the unit internet providers use to advertise connection speed. MB/s stands for megabytes per second and is the unit most operating systems use to show download or file transfer speed. There are 8 bits in a byte, so 1 MB/s equals 8 Mbps.
Internet providers advertise speed in megabits per second (Mbps), but file managers and browsers usually display transfer speed in megabytes per second (MB/s). A 100 Mbps connection has a theoretical maximum of 12.5 MB/s, since 1 byte equals 8 bits, which is why the displayed number looks much lower.
To convert megabits per second (Mbps) to megabytes per second (MB/s), divide the Mbps value by 8. For example, 100 Mbps ÷ 8 = 12.5 MB/s. To convert MB/s to Mbps, multiply by 8.
The Mbps-to-MB/s conversion gives a theoretical maximum. Actual speeds are usually lower due to network overhead, Wi-Fi signal strength, server-side limits, other devices sharing the connection, and general network congestion.
