Country land mass by percentage

Hi there, first time using this forum, so if I'm missing out on a provided link, please don't chew me up.

I am looking for a website that displays the world's geo-political divisions in a percentage form. I have found some in numerical, but in all honesty math frightens me.

I've found out that China is as large as 1/15th of the worlds total land mass, for example. I would like to be able to find a site that would narrow that sort of percentage to 0.02% (I'm thinking Moraco would fit in here).

Thanks for any info you may have!
