in email i have seen that the size say 3k, 4k ETC but what dos this mean in MB and/ or GB?

Answer 1

1k = 1 kilobyte or 1 thousand bytes. generally 1 byte is enough space to store 1 character or letter.

1MB = 1 mega byte or 1 million bytes

1GB = 1 giga byte or billion bytes. , billion = 1000 million

1TB = 1 tera byte or 1000 billion bytes.

incidently , a true kilobyte is actually 1024 bytes not 1000 and all the others , MB, GB, TB are multiples of this .

Answer 2

A 1024 Kilobytes (kb) is a MegaByte (Mb)

A 1024 Megabtyes is a Gigabyte (Gb)

To put in in perspective a letter might be 24kb, a photo might a 3 or 4 Mb and a Movie would be a few Gb.

Hope that helps, Karl.

Answer 3

A bit is the smallest portion of computer memory; it can be set to one or zeo. A byte consists of 8 bits and can store something useful like a single (English) character like the letter "A" (encoded as a number). So your email is made up of a bunch of bytes, each byte storing one letter (this is a simple view but it works for your answer).

A kilobyte (abbreviated Kb or KB) is about 1000 bytes. It is not actually, however exactly 1000 bytes. It is instead 1024 bytes (because memory was and still is often made on 8-byte boundaries, and 128 blocks (another 8-divisible number) of 8 bytes makes 1024 bytes. Thus your email, when it says it is "3k" in size, means that it is 3 kilobytes or 3 * 1024 bytes = 3072 bytes in length.

A megabyte, abbreviated MB or Mb is in reality 1024 kilobytes or 1,048,576 bytes of memory. Similarly, a gigabyte (GB or Gb) is 1024 megabytes or 1,073,741,824 bytes of memory.

So, for a "3kb email" you use 3072 bytes, which is only about
0.003% of a megabyte and a mere 0.0003% of a gigabyte.

Keep in mind that file sizes seen on computer file listings are not always this exact. Your file system (the thing that organizes your files on your hard drive) actually stores data in "blocks" The size of a block depends on your file system among other things, but files, like email, stored on your hard disk are stored in these blocks. This means that if you have an email that says "Hi!", you would use only 3 bytes of space (one for the H, one for the i and one for the !) in memory, but on disk, the file would occupy at least one "block" of disk space wich may be as much as 1-2kb depending on your operating system (Windows/Linux or whatever), original hard disk size, and file system.

This is a very simplistic approach to your question, but I think it answers it fully. There are other considerations, like email file headers, file formats and other issues that cause email files to occupy more bytes than the number of characters present in the message itself, but you need not worry about these issues.

Answer 4

K or k means 1000

SO, 3K is 3 thousand bytes.
a Megabyte is 1000 K or 1 million bytes.
a 3K file size is 0.000003MB (not worth worrying about).

For GB, well 1 GB is 1000 MB, so it is even less to worry about.
A 3K file size is 0.000000003 GB. (like really tiny)
;-)

Answer 5

Neither, the K by itself stands for kilobytes so 3k is 3 kilobytes or 3000 bytes

Answer 6

1,024 kb = 1 mb
1,024 mb = 1 gb
1,024 gb = 1 tb

(You can estimate the size using 1000 for each and usually be close enough)

Answer 7

'k' means kilo you fool,

dat means 1000k = 1MB
1000 000k = 1000MB = 1GB


(to be accurate, 1024k = 1MB)
