School bus
≈12.2 mA full-size school bus, useful as a measuring stick for dinosaurs, whales and buildings.
≈12.2 m → 8,848.86 m
Monumental scale
Engineering, mountains and the vertical ocean.
Human construction, biological records and Earth’s vertical extremes meet in this realm. Height and depth are kept semantically distinct even when their metre values can be compared.

Eiffel Tower
330 mParis’s iron landmark including its modern antenna height.
102.5 m · Ocean
Deepest open-circuit scuba dive
332.35 mA record-setting open-circuit scuba descent that pushes human physiology and equipment far beyond recreation.

103.6 m · Ocean
Titanic wreck depth
≈3.8 km deepThe Titanic rests in darkness under enormous pressure on the North Atlantic seafloor.
103.7 m · Earth
Mont Blanc
≈4.807 kmThe Alps’ highest summit, whose snow-and-ice cap makes the measured altitude vary between surveys.
103.8 m · Ocean
