MBPS vs MbPS

MBPS or MB/s is MegaBytes Per Second

MbPS or Mb/s is MegaBits Per Second

1 Byte = 1 Bits

1 MB/s = 8 Mb/s

Verbally MBPS & MbPS both sound the same.

Ad campaigns of telecom companies take full advantage of this when advertising network speeds. In ads speeds are expressed in Mb/s to make the number seem 8 times larger.

It's misleading to express speeds in bits because day-to-day we refer to data size in bytes.

Let's take a scenario of downloading a file of 1 GB.

1 Giga Bytes (GB) = 1024 Mega Bytes (MB)

If speed was expressed consistently in Bytes, & we had speed of 5 MB/s it would take 204.8 seconds to download the file.

But since the speed is deceptively expressed in Bits, & we assume a speed of 10 Mb/s. The speed number(10) is twice the previous(5) but the unit is in Bits. It would take 819.2 seconds to download the 1 GB file.

This is because 10 Mb/s = 1.25 MB/s.

Anyone who may miss the small difference between 'B' & 'b' would expect 10 Mb/s to be better than 5 MB/s.
