34,000 psi
A one foot liquid head of water will exert a force of 1.04167 psi. 27.7 inches of water = 1 psig... Mean and dirty 1foot=1/2psig
divide by 27 = 1.185
4.0kg per square cm equates to approximately 57 pounds per square inch.

Your question does not contain enough information to answer. But . . . let's assume that the 5,000 pounds is spread out over a flat surface measuring 50 ft x 100 ft. That equals 5,000 square feet. 5,000/5,000 square feet = 1. So our 5,000 pounds would exert exactly 1 pound per square foot at every point. Let's next say that we spread out the 5,000 pound, but thicker, on a flat surface measuring 25 feet x 50 ft. That equals 1,250 square feet. So our 5,000 pounds is now supported by only 1,250 square feet. We know by looking at it that each square foot will support more of the weight than in the first example. 5,000/1,250 = 4. So our 5,000 pounds in this case would exert exactly 4 pounds per square foot. Carried to an extreme, let's say our 5,000 pounds sits on just one square foot of flat surface. 5,000/1 = 5,000 pounds per square foot. Even crazier, our 5,000 pounds might sit on just a 6 inch x 6 inch flat surface. 6" = 0.25 square feet. So, once again, 5,000/.25 = 20,000 pounds per square foot.
27 lbs
About 1/2 pound.
About 14,000 pounds per square inch
8 pounds i guess
4000
1kg per sq cm is equal to about 14.2 pounds per sq inch.
From the NASA link, below: "Earth's atmosphere is pressing against each square inch of you with a force of 1 kilogram per square centimeter (14.7 pounds per square inch)."
250 pounds per square inch.

Atmosphere pressure can be measured in pounds per square inch, and this varies depending on how far a location is above or below sea level. At sea level, atmospheric pressure equals 14.7 pounds per square inch (or psi).
