Find Linux specific capacity files

When the file capacity is percent_val and a specific capacity criterion is limit, the command to find and output all files whose percent_val is limit or higher is

find ./* -size "$percent_val" >= "$limit"

Is this right?

And is the code below the command to delete the file with a specific capacity or more found capacity?

find ./* -size "$percent_val" >= "$limit" -type f -ls -exec rm -rf {} \;
