The lb (Pound) is a unit of mass (sometimes called weight) and the psi (pounds per square inch) is a unit of pressure. I take it that you need to calculate the pressure of a number of pounds on a certain surface. You may find the suggested web site helpful. You can't convert pounds to pounds per square inch (psi). One is force and one is pressure. If you know the area over which the force is spread, then you can divide the force by the area and get pounds per square inch (psi).
psi of pressure = (200 lbs) divided by (the area that supports the 200 lbs, in inches)
Multiply psi x 0.07 to get atmospheres.
No, It is not possible as they measure different things. Pounds is a measurement of force and psi is a measurement of pressure. This problem is similar to asking if feet can be converted to gallons.
200lbs
1 ATM = 101325 Pascals 1 Pascal = 1/101325 ATM
yes
Multiply psi x 0.07 to get atmospheres.
Multiply psi by 0.006894759086775369 to convert from psi to MPa. ex: 1000 psi = 1000 x 0.006894759086775369 = 6.89 MPa http://www.chapelsteel.com/psi-mpai.html
Multiply by 2.03625437 to convert from psi to inches mercury. Multiply by 0.49109777 to convert from inches mercury to psi.
1 bar = 14.5 PSI
752 Torr = ~14.54 psi
110 - 130 Scfn is what in psi
1 psi = 64984.65 Pa Therefore 50 MPa = 769 Psi
Multiply psi by 144 to get psf.
95 psi = 6.6 bar
How to convert wog to psi? For example 1000 wog how much psi?
Inches of mercury x 0.4912 = psi
(1 kPa = 0.145038 psi). So, 220 kPa x 0.145038 = 31.9083 psi
