Mbps to MB/s Converter

To convert megabits per second (Mbps) to megabytes per second (MB/s), divide by 8. For example, a 100 Mbps internet connection can theoretically transfer 12.5 MB per second, before overhead.

Mbps to MB/s conversion table

Mbps vs MB/s: what is the difference?

Mbps measures millions of bits per second and is commonly used for network bandwidth. MB/s measures millions of bytes per second and is commonly used for file transfer. A byte contains 8 bits. Capital B means bytes; lowercase b means bits. Both units in this table use decimal prefixes.

Why is my download slower than the table?

These figures assume the full advertised link speed is available for file data. TCP/IP and other protocol overhead, Wi-Fi interference, server limits, disk speed, congestion and latency can reduce sustained throughput. An internet plan advertised as 1 Gbps does not guarantee a 125 MB/s download.

Convert speed into transfer time

For a 100 GB decimal file on a 500 Mbps link, the ideal transfer time is 1,600 seconds (26 minutes 40 seconds). At 80% efficiency it becomes 2,000 seconds (33 minutes 20 seconds). Use the guides below to compare other file sizes and links.
