1MPa is approximately equal to several meters of water column.

Megapascals and meters are both units of pressure measurement.

Because1MPa =1000kpa =1000000pa,

And 1KPa= 100 mm water column,1pa = 0.001kpa = 0.001x100 mm water column =0. 1 mm water column =

Therefore,1MPa =100000pa =100000x0.0001m water column = 100m water column.

1,1ATM = 0.1MPa =100kpa =1bar =10m water column =14.5psi =1kg. In order to facilitate memory, it can be simplified as follows:

2、 1 kpa = 0.0 1 bar = 10 mbar = 7.5 mmhg = 0.3 inhg = 7.5 torr = 100 mmh2o = 4 inh 2

1Gpa= 1000MPa

1Mpa= 1000000Pa

1Pa= 1N/m？

In the formation conditions of neutron stars, the energy density reaches the critical pressure, which means that the unit of pressure is the same as the unit of energy volume density. This relationship can be inferred from statistical physics.
