How much does the Earths Atmosphere weigh? Also let us know how to calculate that.

\sim 5 \cdot 10^{18} \ Kg.

What's the definition of atmospherical pressure ?

[NateTG]

Isn't what you're listing the mass, rather than the weight of the atmosphere?

I would be inclined to multiply 19 PSI by the surface area of the earth.

 

[krab]

NateTG's right, except that atmospheric pressure is 14.7 PSI.

 

[chroot]

You mean 14.7 psi, NateTG. I'd be inclined to do the same.

atmospheric pressure is 101325 Pascal. i don't know the wieght.

 

[yourdadonapogostick]

if post #2 is right then it wieghs about 5x10^19Newtons

atmospheric pressure is 101325 Pascal. i don't know the wieght.

to many numbers, i think 10^5 Pa will be good enough.
