How to find files in a directory that are larger than certain size?

I have many files under a directory. How to find those files under the directory that are larger than certain size, say 500MB?

Find the files that are larger than 500MB in the current directory (./):

find ./ -size +500M

Prints our more information about these files:

find ./ -size +500M -exec ls -lh {} ;

Or, more conveniently, sort these results by file sizes:

(find ./ -size +100M -exec ls -lh {} ;) | sort -rh

very good answer. Thank you
