how many KB to equal a mb?

1024

It all depends if you are selling the space or using it.

Computers use a language called binary, (base 2) and so any numbers they use and store tend to be values of 2 to various factors, 2, 4, 8, 16, 32, 64 and so on. A computer inthis way cannot store a value of 1000, but can do 1024, hence 1024 bytes = 1 Kilobyte, and 1024 kilobytes (1024 * 1024 Bytes) = 1 megabyte.

Now getting back to my point of the value depending on if you are using or selling, is quite simple. Lets imagine for example that you are buying a hard disk drive, that has been advertised as 20 Megabyte (i know its small and you wouldn't but i'm using it to illustrate something). In reality it would probably be about 20 Million bytes in size, however that would only equate to about 19.5 Megabytes.

1024 = 1KB

1024 * 1000 = 1024000 KB = 1MB

1000 MB * 1024 = 1048576 MB = 1 GB

1024 KB is 1 MB

1024 KB make up a MB

2^10 = 1024

I m trying to chop down a video that is 71,766,188 KB to increments of 500 MB. How do I do this?

A topic of much confusion, apparently. First I'd like to point out that there is a major difference between a "kB" and a "kb", as well as a major difference between a "MB" and a "Mb."

Kilobyte (kB), equal to 1,000 bytes, or Kibibyte (KiB), equal to 1,024 bytes.

Kilobit (kb), equal to 1,000 bits, or Kibibit (Kib), equal to 1,024 bits.

Megabit (1,000,000 bits) or mebibit (220 = 1,048,576 bits); the preferred symbols are Mb and Mibit, respectively¹

MegaByte (1,000,000 bytes) or mebibyte (220 = 1,048,576 bytes); the preferred symbols are MB and MiB, respectively¹

1024

The truth is: computers count 1024, and HD manufacturers use 1000. You lose 24kb per mb .
