The deepest point of the trench is more than 2 km (1.2 mi) farther from sea level than the peak of Mount Everest. [a] At the bottom of the trench, the water column above exerts a pressure of 1,086 bar (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%.
