Q: Also what's 21,824 KB expressed in megabytes? Thank You
A: 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!
