Memory Never Correct

[Shadow Ghost]

how come when ever you buy something meory related no matter what it be SD card, Ram, Hard drive, USB it's never the amount your pay for sometimes not even close for instance 
i have a 2TB(1.81GB) and a 500GB(465GB) Hard drive and i have 16GB(15.9GB) of RAM installed and a USB drive 16GB(14.7GB) and i recently bought a 4TB HDD and it was 3.62GB like what in the hell is this SORCERY where is like My 380GB at................ the least people could do is make the memory a little over instead of completely ripping you off

Windows counts in different units (GiB) but incorrectly reports the unit of measurement as GB. If you convert the numbers in Windows to real GB, you'll see it's the correct value (i.e. 1.81GiB == 2000GB == 2TB).

 

Or you can try plugging into any operating system besides Windows, such as OS X or Ubuntu and again you'll see it displayed correctly.

For RAM it's right, the missing 100 MB might be: 1-For iGPU 2-Hardware reserved

and for storage, they use decimal base not binary, for example 1 GB = 1000000000 B

so i have to basically use a different OS to even access the memory it's not counting and if it uses decimals wouldn't that make it more accurate instead of rounding to the nearest number

It's not that the memory is not being counted, it's just being measured in a different unit than the one reported. Your hard drive may say 465GB but that's not really the number of GB. Windows is measuring something different (called GiB) and telling you it's the number of GB. If you convert 465GiB to GB then you'll get 500.

 

A 500GB hard drive has 500,000,000,000 bytes (500 billion). It's a bit tedious to write that every time, so instead of writing "500,000,000,000 byte hard drive" we use some shorthands. We define "GB" as a shorthand for 1,000,000,000 (1 billion) bytes, and so we could write this hard drive as a 500GB hard drive (500 groups of 1,000,000,000 bytes).

 

Windows counts in groups of 1,073,741,824 bytes, which we call "GiB". Since this group is larger than the other one, it doesn't take quite as many of them to get your total amount. So if you count using these groups, you'll find that 500,000,000,000 bytes is about 465.6 groups of 1,073,741,824 bytes, or 465.6GiB.

 

You can do the math in reverse, and see that 465.6GiB, where a GiB is a shorthand for a group of 1,073,741,824 bytes, is simply (465.6 x 1,073,741,824) = ~500,000,000,000.

 

 

Only thing is that Windows reports all its measurements as "GB" even though it's actually telling you the number of GiB.

Very interesting .... tryed to fill up my USB as much as i could the byte are closer to 16 but still don't seen to add up to 16GB or do i need to convert this

No, that looks about correct, 15.85GB capacity. A small portion of the 16GB won't be available for storage.
