Orders of magnitude (pressure)

Pressure	Item
20 µPa	Threshold of human hearing. Air pressure oscillations of this amplitude, at frequencies between 1 and 5 kHz, are the smallest the ear can hear in a noiseless environment.
0.5 Pa	Atmospheric pressure on Pluto (1988 figure; very roughly).
1 Pa	Pressure exerted by a house fly standing on a postage stamp in vacuum (roughly).
10 Pa	Pressure increase per millimeter of a water column (roughly).¹
100 Pa	Threshold of pain. Sounds above this amplitude are unbearable and can cause ear pain. Prolonged exposure may lead to hearing loss.
1 kPa	Atmospheric pressure on Mars; 1 % of atmospheric sea-level pressure on Earth.
10 kPa	Pressure increase per meter of a water column¹, or the drop in air pressure when going from earth sea level to 1000 m elevation.
101.325 kPa	Standard atmospheric pressure for earth sea level = 1013.25 hPa.
180 to 250 kPa	Pressure in an automobile tire.
0.8 to 2 MPa	Pressure used in boilers of steam locomotives.
9 MPa	Atmospheric pressure on Venus
10 MPa	Pressure washers force out water at this pressure.
12 MPa	Pressure exerted by a 60kg woman wearing stilettos.
20 MPa	Pressure of a typical aluminium scuba tank.
100 MPa	Pressure at bottom of Mariana Trench, about 10 km below ocean surface.
10 GPa	Pressure at which diamond forms.
100 GPa	Theoretical tensile strength of a carbon nanotube (CNT).
530 TPa	Pressure inside an Ivy Mike-like nuclear bomb
6.4 PPa	Pressure inside a W80 warhead detonation
35 PPa	Pressure inside the core of the Sun

4.63 × 10¹¹³ Pa	The Planck pressure
