How many megabytes in a GB?

Question

Also what's 21,824 KB expressed in megabytes?

Thank You

Answer 1

Okay, this is a list of the measurements used in Hard Drives and RAM:

Bit: the lowest denomination; it can either be on or off (in binary, this would be either 1 or 0)

1 Byte = 8 bits.

1 Kilobyte (KB) = 1024 bytes

1 Megabyte (MB) = 1024 KB

1 Gigabyte (GB) = 1024 MB

1 Terabyte (TB) = 1024 GB

And so on.  So, 21,824 KB would be about 21.32 MB.  But remember, when buying something like a hard drive the actual formatted capacity (i.e. the OS you've installed on the computer, like Windows, Mac OS X, or Linux).  This equation works for Mac formatted drives, so you can know how much space you're actually getting.

Equation:

8*1024^3*(advertised hard drive space)

8 stands for the amount of bits in a byte, and 1024^3 (1024*1024*1024) represents the movement to KB, MB, and GB. Then you take the advertised hard drive space (in this example, we'll use 250).  So, after installing Mac OS X, roughly 214.74 GB is usable on your hard drive.  I hope this helps.

Good luck!

Answer 2

There are two answers to this question. Megabyte is used both for refuring to 10^6 = 1,000,000 bytes, or 2^20 = 1,048,576 bytes.

The IEC, IEEE, EU and NIST are now differentiating the two by calling 2^20 a mebibyte(MiB). However this is not used everywhere, for example your file manager that shows file sizes in MB.

So there are 1,000 GB in a MB, or 1024 MiB in a GiB.

The second part of your question, the respective answers are 21.824 MB and  21.3125 MiB

I hope I've made that clear.

Answer 3

1000mb = 1 GB

21,824 KB = 21mb  

Answer 4

The correct answer to the first part of your question is:

1024MB = 1GB

in fact the same goes all the way down the scale:

1024KB = 1MB

1024B = 1KB

Based on that assumption 21,824kb = 21.3125Mb as you would divide 21,824 by 1024.

Most computer hardware manufacturers do round the 1024 down to 1000 however (even though it is incorrect). So the commercial Gb is described as 1000Mb. This is why when you get a 160Gb hard drive it'll show up on your pc as only being somewhere in the region of 149Gb!

Answer 5

1000 ish

Answer 6

1000

Answer 7

1024

Answer 8

1024 and 21.31 Mbs

Answer 9

1,024.

Answer 10

1024 kb in a mb 1024 mb in a gd 1024 gb in a tb

Answer 11

they all go by 1000s so that is 21.824 MBs

Answer 12

2^10 = one thousand twenty-four

Answer 13

1Gig = 1024meg

21,824kb = 21.824Meg

kenny

Answer 14

theres 1024MB in 1GB

Answer 15

In real binary counting one Gigabyte is 1,024 megabytes.

In advertising, it is only 1000 nominally.

In binary, two digits are a bit. 8 bits are a byte.

A kilobyte is 1024 bytes.  When you ad a digit,  you double the possible sequence of "memory" or operations.  See it goes like this.

2,4,8,16,32,64,128,256,512,1024.  1024 is 2^10.

Only when the numbers become so complex and statisticaly normalized did Marketing and Legalease come into the advertising aspect of renaming the amounts.  remember when the 1.44 Mb floppys came out.  They had to be 1.44 MB average on the producton line.  I've had disks as low as 900kb and as high as 1.6Mb.

Answer 16

Some will say there are 1000 MB in a GB, others will say 1024.  For instance, Windows uses the 1024 figure, but hard drive manufacturers use 1000.

Ditto for how many KB in a MB.

So, 21824KB = 21.824MB if you're using the 1000 number, or about 21.3MB if you're using 1024.

Answer 17

There are 1024 Megabytes in a Gigabyte.

21824 KB = 21.3125 MB

Answer 18

1GB= 1,024,000 KB = 1,024 MB

(100 MB = 102,400

   50 MB = 51,200)

21,824 KB = 21.31 MB

Answer 19

1,000 MB = 1 GB

Answer 20

1000

21MB

Answer 21

1000 and 21.824 megabytes
