The World's Tallest Mountain

I love factoids like this.

The World's tallest mountain depends upon measurement.

• Mount Everest is 8,840m above sea level.
• Mauna Kea is 10,203m above its base on the floor of the Pacific Ocean.
• Chimborazo is 6,384,000m from the centre of the Earth.
  

There. That should sustain your next dinner conversation for at least 10 minutes.
