In appearing knowledgeable and figuring out questions related to our planet, geography and distance, it helps to know a few handy numbers / simple stats. On this pages I've included what I consider some important stats to know (but many of which I forget). Since I grew up in Australia you'll notice all the measurements in metric units, but since I live in the states now you'll notice I also pay attention to the US and Australia.
