None.
A newton is a measure of force, whereas pounds per square inch in a measure of pressure. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
8.851 inch-pounds = 1 Newton-meter so 885.1 inch pounds
10 inch-pounds is approximately 1.13nM
You could have 'newton-centimeters', or 'newton-inches', or 'pound meters' etc., but you can't have 'newton pounds'. Torque is (a distance) x (a force), but 'newton pound' is (force) x (force). Whether or not that has any physical significance at all, it's surely not torque.
About 1/2 pound.
To convert pounds per square feet to pounds per square inch, you need to divide by 144 since there are 144 square inches in a square foot. In this case, 32 pounds per square foot would be equal to 0.222 pounds per square inch.
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.
