      Hey jonochau,

      I’ll admit, I had to look this one up!

      The Earth has a surface area of 510,082,000 km2 – wow!!!

      29.1 % of this is land, whereas 361,900,000 km2 of it is water (70.9%)!

      There you go – we both learned something today lol!

      Hi jonochau,
      Here are the figures, I got fresh from the world figure internet site 😛

      Entire World 196,940,000 square miles (so one square mile is the size of a large town)

      That massive, but let’s break it down
      Total Land of the world is 57,506,000 square miles
      and Total Water is 139,434,000 square miles

      Much more water than land, and its rising – better getting my swimming costume on 😛

      Hi jonochau,
      Great name!

      These are just estimations though. The Earth is covered in mountains, valleys and other bumps and dips which increase the usable surface area. The more accurately they are measured, the larger the surface area of the Earth appears. So if one were to measure so accurately as to be taking the bumpiness of individual molecules into account, then the eventual surface area of the Earth would be significantly larger than the above answers.
