in metric units if possible.

dear sensible_man
i want to know the presure per cubic centimeter and does fishes feel happier in deeper aquariums or not.so i should use a formula and aquation.
by the way is density a question it self?
imean salt water and fresh water.please advise.

The weight of the water in pounds per gallon multiplied times the depth of the water multiplied times 0.052 will give you PSI at the depth used.
fresh water is 8.34 pounds per gallon

This sounds like a homework problem so I'll only hint. Water weighs something per CuFt or something per unit volume.
Gravity acts on that weight. The floor of the aquarium has an area, So it's the weight of the water acting on the floor of the aquarium. The answer needs to be normalized. Answer can be in PSIG or Pascals in metric units. I'd estimate somewhere near 60 lbs/sqft without doing any calculations for a 10 gallon tank. Again wrong units on purpose.

The general rule is 1 foot of water for every pound per square inch (PSI). So, at 10 foot depth (3 meters), the pressure will be 10 PSI. You can use this calculator to get whatever units you're looking for: http://www.allconversions.com/

A gallon of water weighs 10 ibs. a pint of water weighs a pound and a quarter. Hope this helps.

Not sure what you are trying to find. Please add info to your question to get an answer. Are you trying to find the weight of the water or pressure exerted on the bottom of the vessel?
