According to Guinness:

>If you're wondering why we’re not talking about Mount Everest, it comes down to size vs altitude. Soaring to 8,848.8 m (29,031 ft) above sea level (asl), Everest – aka Chomolungma or Sagarmāthā – is the world's highest mountain. (Incidentally, Vescovo has also climbed that, back in 2012, which makes him the first person to visit Earth’s highest and lowest points, but that's a whole other story.)

>The top of Mauna Kea falls far below the lofty zenith of its Himalayan rival, however it is more than a kilometre taller than Everest when comparing the two from base to pinnacle.

>But more than half of this dormant volcano lies unseen underwater. Indeed, of Mauna Kea’s c. 10,211 m (33,500 ft) total height, only 4,207 m (13,802 ft) is above the sea. This makes it half the height of the iconic "8,000ers" – the 14 mountains that stretch in excess of 8,000 m (26,247 ft) asl.
