Are we really getting 60GB?

I just checked my usage and noticed on the side of the page that Plusnet defines 1MB as 1000 kB and 1GB as 1000 MB.
This is not true. 1MB is 1024 kB and 1GB is 1024 MB.
By Plusnet's definition, 60 GB is 60,000,000 kB
By the REAL, correct definition 60GB is 64,424,509 kB. Which means we are losing out on over 4 GB. and the actual allowance we are getting is 55.88 GB

This is pretty much industry standard so don't worry about it.

Using this notation a “kbyte” unambiguously has 1000 byte, and no assertion is made about the meaning of “KByte”.
According to a decision of the International Electrotechnical Commission  as of 1998, the kibibyte should be used instead of the Kbyte

Re: Are we really getting 60GB?

Hard disk manufacturers have been using the 1000 based units since, well, always.
The correct abbreviations are GB for the 1000 based units and GiB for the 1024 based units.

Re: Are we really getting 60GB?

Have you ever noticed that a 16GB USB Flash device actually only has around 15GB available for storage !
I also use two identical 8GB USB Flash drives in one of my PVR's, one has 7.5GB available, the other 7.25GB available.
So, I would accept 10GB or 60GB as being "shorthand" for being around that capacity !
So ends my Tirade Descriptions Act !

Re: Are we really getting 60GB?

I hate to be pedantic (although many of my friends would disagree), but I'm afraid that the Trade Descriptions Act has been repealed to all intents and purposes.  The new piece of European legislation that has replaced it is the Consumer Protection From Unfair Trading Regulations   Huh (It's not quite straight swap. Undecided  )

Not for the want of crooks or legislation to enforce - budgets? - that's a different story.  Undecided

This is not true.

Yes, it is true!
It is generally only computer memory that uses kB, MB and GB to mean powers of 2 rather than powers of 10, communications speeds and hard disk capacities have always used powers of 10, back in the kB and MB days the difference was slight so could often be disregarded, now in the era of GB and TB, the difference is more noticeable.
Have a search for kibibyte, mebibyte and gibibyte as the correct units rather than kilobyte, megabyte and gigabyte, these are abbreviated as kiB MiB and GiB, rather than kB, MB and GB

kibibyte is a multiple of the unit byte for quantities of digital information. The binary prefix kibi means 1024; therefore, 1 kibibyte is 1024bytes. The unit symbol for the kibibyte is KiB.[1] The unit was established by the International Electrotechnical Commission (IEC) in 1999[2]

thing is some of us (lots actually) were using PCs and electronics LONG before 1999
the terms used above USED to be correct, then they were dumbed down, then new terms invented to justify the hi-jacking of the old terms

Re: Are we really getting 60GB?

As andyburns points out - communications speeds are always stated in multiples of 1000 - and includes all ADSL and FTTC speeds. This certainly goes back to when voice channels were called 64kbps (8 bits, sampled at 8kHz), and possibly earlier.
Of course, it makes it even harder to work out download speeds when you measure the transfer based on file sizes - which are another commodity measured in 1024's.

Re: Are we really getting 60GB?

Tsk - forget 60GBps; I've just been reading that BT will offer small/medium businesses 300 GBps within a year or so. Speculation is that it will be less than £100 a month.
Now Zen, but a +Net residue.

Someone should tell the thinkbroadband speed tester about that!
