Simon, Isn't there a power law distribution of some kind with larger and smaller grains intermixed? Compare the definitions of "sand", "silt" and "clay", or look up "sediment grain sizes".

Hello ,
I read recently that the calculated the approx. amount of stars in the known universe to be 7x10^22, which is according to source, greater than the number of grains of sand in all the deserts and beaches on earth.
Well, this is quite big, but as I was explaining this to some people around me,
is there a known value of the number of grains of sand in let's say 1 cubic meter of sand ? I know some are very small and others are bigger : does someone has an approximate value ? I tried to find without success and also I have no idea on how to calculate this simple value.
Thanks for any answer(!).

best regards and have a nice evening.
