Came across an interesting estimate.

Imagine that you've extracted all of the salt from all of the oceans and sprinkled it over all of the world's dry land masses. How deep would such a layer of salt be?

My Guess a kilometer

Source? (Or sauce?)

my guess is that it would be 3.5987kms thick

Using the following rough data estimates (drawn from memory):Ocean salinity (by mass) cs = 3% = 0.03Fraction of Earth’s surface covered in sea/ocean fw = 70% = 0.7Average ocean depth dw = 3,000 metresOcean water density ρw = 1 ton/m3Density of granular salt ρs = 1.3 ton/m3
yields a salt depth of ds = 162 metres.

(I leave it as an exercise for the reader to derive the simple formula relating ds to the other variables.)
