It's a half gig. To convert MB to GB move the decimal point three places to the left, so 512 MB becomes .512 GB. To convert MB to KB move the decimal point three places to the right, so 512 MB becomes 512,000 KB<br />
<br />
To convert a whole number to K, move the decimal point three places to the left.<br />
To convert a whole number to M, move the decimal point six places to the left.<br />
To convert a whole number to G, move the decimal point nine places to the left.<br />
<br />
Thus 1,000,000,000 Bytes equals<br />
<br />
1,000,000 KB or<br />
<br />
1,000 MB or<br />
<br />
1 GB<br />

Because computer math isn't ba<x>se 10, it's hexidecimal...<br />
<br />
<br />
...a gigabyte isn't actually 1,000,000,000 (the actual number is 1,073,741,824) but the the numbers are large enough that few people can conceptualize them and because we tend to think in ba<x>se 10, the convention is to speak of kilobytes, megabytes or gigabytes as though they were simple things while privately acknowledging that they're anything but.

Half a gig babe....<br />
