About 100mbit = 12.5mbyte.

Bit is 1/8 of byte.

Also this isn't exact numbers as your internet speeds flex, as you may get high as 140/41mbit

cool! better than now 3.8mb

In theory 100MBit = 11.9MiByte

But getting those 11.9 depends on..
.. the quality of the connection at your Home.
.. the capacity of you chosen steam server at any given time.

NO it's 12.5MB/s (or approx 750MB/minute)

Byte doesn't use the decimal system. To be acurate you gotta calc it down to Bit, transfer to Byte and than divide by 1024.

100*1.000*1.000 = 100.000.000 Bit
100.000.000 / 8 = 12.500.000 Byte
12.500.000 / 1.024 / 1.024 = 11.92 MiByte

The ISP already factors that in;

Thats why on 120mbit; I'm getting 15MB actual all the time

They can't factor it in. GigaBit and GebiByte are different units. And unlike HDD manufaturers ISP don't try to confuse customers usually. Just means you got a bit more than your paying for. :)

Me i'm on a 50MBit connection and i don't get the whole 5.96MiByte/s that i should. Only ever 5.6ish. While by the laymans calc i should be getting 6.25.

Well you're just not getting full speed your ISP says you get; I do... that's all there is to it.

12.500.000 / 1.024 / 1.024 = 11.92 MiByte

All the other factors that affect what speed you will actually get at any given time make all the above completely irrelevant detail. You are being "precise", not "accurate".

That's the protocol overhead, if you were to look at the raw data transfer, you'd be getting the full 5.96, but steam, and virtually any other download tool/report, measures the download rate of the actual content.

As for Giga v Gibi, don't trust that too much. Giga is still very commonly used for both. The binary prefix standard by the IEC never really took off.
