How fast is 10mbs and 100mbs relative to megabytes? Is there a formula to use?

I think that it is commonly believed to be 10 MB per second or 100 MB per second - But I have my doubts.

10mbps should be written 10Mbps and is "10 megabits per second"
100mbps should be written 100Mbps and is "100 megabits per second"
(The lower case "m" technically refers to "milli-", so 10mbps is technically 10 milli-bits per second, or 10 1000'ths of one bit, per second - disgustingly slow.)

Assuming 8 bits per byte, 10Mbps is 1.25 MBps (megaBYTES per second), and 100Mbps is 12.5 MBps.

These are all RATES of data transfer.

A MEGABYTE is a "quantity" of data.

As in: it is 1672 kilometers from Here to There. At a rate of 100 kilometers per hour, it will take 1.672 hours to get There, from Here.

Why rant on? Because one day, if it hasn't happened already, somebody is going to make a costly mistake with all this sloppiness about getting MB, Mb, MBps and mbps all mixed up!

First, be careful of capitalisation... Mbps and MBps are two different items.

Mbps = megabits per second. Since there are (usually) 8 bits in a byte 10Mbps is approximately 1.25 megabytes per second.

NOTE: sometimes it takes more than 8 bits to transfer a byte of data - for example if you are using an 8 bit mode with parity and stop bits you may have to transfer 10 or more bits of information for each byte of data.

MBps = Megabytes (1024 bytes) per second. Obviously the conversion forthis is trivial!

Hope this helps,

I'm not going to bother with minor details like mbs or Mbps blah blah.
The theoretical difference is 100Mbps is 10 times faster than 10Mbps, however this varies depending on;
Amount of machines accessing the network,
Distance over the whole network,
Speed of machines,
and many other factors.
Hope this helped,
