Pounds per sq in is a measure of pressure while 1600 sq inches is a measure of area. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
It ranges from 0.033 pounds per cubic inch to 0.043 pounds per cubic inch.
Given that there are 144 square inches per square foot, 100,000 pounds per sqaure foot equals 694.44 pounds per square inch.
Multiply by 144, since there are 144 square inches in a square foot (12x12).
Uranium has a density of 19 grams per cubic centimeter, so you'll have to convert the grams to pounds and the cubic centimeters to cubic inches. Since 1g = 0.00220462280lb, then 19g = 19 x 0.00220462280lb, which = 0.041887833lb, or about .042lb. Now convert cubic centimeters to cubic inches: 1 cubic centimeter = 0.061023744100 cubic Inches = about .061 cubic inches 19g/cc is the equivalent of .042lb/.061 cubic inches, which divides out to about .69 pounds per cubic inch.
A foot-pound is not a pound per foot, it is a pound times a foot. So the units are not the same. The question has no answer. It is like asking how to convert feet to pounds or seconds to inches.
2,200/1,600 = 1.375 psi
16 pounds per foot equals 1.33 pounds per inch.
(1,500 pounds) x (60 inches) / (12 inches per foot) = 7,500 foot-pounds
Inches of water x 0.03613 equals pounds per square inch (psi).
It ranges from 0.033 pounds per cubic inch to 0.043 pounds per cubic inch.
If the material is water, that is also 1,600 cc.
If you are referring to 27' 9" head of water at 39.2F, then the pressure will be 12.0158 pounds per square inch at the base. 1 ft. of head x 0.433 = pressure in lbs/sq.in.
Given that there are 144 square inches per square foot, 100,000 pounds per sqaure foot equals 694.44 pounds per square inch.
There are 36 inches in a yard (12 inches per foot times 3 feet per yard), so a square yard is 36 times 36 or 1,296 square inches. So 1,600 square inches is greater.
10 ft x 12ft x 72 inches/12 inches/foot = 720 cu ft There is 105 pounds of gravel per cu ft, or 105* 720 = 75,600 pounds At 2000 pounds per ton, that is 75600/2000 = 37.8 tons
1600 meters in a mile. 5280 ft in a mile. 5280 divided by 1600 equals 3.3. So there are 3.3 feet in every meter. 12 inches in each foot means 39.6 inches per meter. 100 cm's per meter or 39.6 inches per 100 cm's which can be written as 100/39.6 which equals 2.52525 or 2.53. This means there are approximately 2.53 cm's in every inch. So 228 /2.53 equals 90.11858 or 90.12 inches in 228 cm's.
Multiply by 144, since there are 144 square inches in a square foot (12x12).
