Converting from 1000 to 1024 bytes

Question

I'm trying to convert a size, say 244410368 bytes to megabytes xxxxxx (MB), but I have no idea how to do this.

I find the idea of ​​1000 and 1024 bytes / bit quite confusing.

Answer 1

Although unit conversion is not terribly complicated math, reducing the number of hard-coded numbers and shell scripts may be an idea (rather than a calculation). If your linux system has a units program, you can do unit conversions as follows:

 % units --terse "244410368 bytes" "MiB" 233.08789 % units --terse "244410368 bytes" "MB" 244.41037 

(In Ubuntu, the units program is provided by the (surprise!) units package.)

Answer 2

The de facto size for a byte is 8 bits, so just convert by 8 to convert the number of bytes into several bits.

Answer 3

This should be true for the edited question:

1MiB = 1024 * 1024 B, therefore:

244410368 B = 244410368 / (1024 * 1024) MiB, therefore:

244410368 B = ~ 233 MiB

(please do not modify your questions in such a way as to completely change their meaning, this is confusing, and now all previously good answers are invalid, you can close (or just leave) the question and ask another question)

Answer 4

1 byte - 8 bits. http://www.google.com/search?q=1+byte+in+bits

1000 versus 1024 is mega / gigabyte / terabyte in bytes, and this is really confusing (especially when you talk about hard drive capacity).

Answer 5

So, megabytes are 1000 * 1000 bytes, and Mebibyte is 1024 * 1024 bytes. So, to turn 244410368 bytes into the MiB section on 1048576 (1024 * 1024). Hope this helps a bit.

In addition, if you want to convert MB to MiB, multiply it by 1000000 and divide by 1048576. This is the difference between them.

Answer 6

Easy

 244,410,368 bytes * 8 = 1,955,282,944 bits 

You see that the byte is 8 bits, so multiplying it by 8 will give you the answer.

Answer 7

See this wiki link: http://en.wikipedia.org/wiki/Byte

Now there are 8 bits in one byte.

So, multiply by 8;)

Answer 8

 bits=$((${bytes}*8)) 

Answer 9

There are 8 bits in the byte. If your units are raw bytes, you can simply multiply by 8 to get the bit. 1024 numbers do not take effect until you deal with prefixes. For example, a kilobyte is 1024 bytes. Wikipedia has a nice table.

Answer 10

The story of K (Kilo) in IT means 2 ^ 10, M (Mega) - 2 ^ 20, G (Giga) - 2 ^ 30, and T (Tera) - 2 ^ 40, etc. You can use the calculator to do this: "select a scientific representation, then click" Hex or Bit ", enter the number, and then click" Dec "

The number up to K divided by 2 ^ 10, K by the number times 2 ^ 10

Divide the number in M ​​by 2 ^ 20, M by the number multiplied by 2 ^ 20

Divide the number in G by 2 ^ 30, G by the number multiplied by 2 ^ 30

The number before T divides by 2 ^ 40, T by the number times 2 ^ 40

Break a bit into bytes by 8, multiply a bit by 8 by 8

Answer 11

8 bits = 1 byte 1024 bytes = 1 KB 1024 KB = 1 MB 1024 MB = 1 GB

So, 1 GB = 1024 * 1024 * 1024 * 8 bits.
