Enter a value and pick its unit (bits/s, Mbps, Gbps, bytes/s, MB/s, GB/s), and the tool converts it to every other bandwidth unit live.
There are 8 bits in a byte, so divide the bit rate by 8: 100 Mbps ÷ 8 = 12.5 MB/s.
Mbps is megabits per second (network speed); MBps or MB/s is megabytes per second (file transfer). 1 MB/s = 8 Mbps.
At 100 Mbps (12.5 MB/s), 1 GB takes about 80 seconds ignoring overhead.
