You cannot convert "Newton meters" to psi. psi is a pressure and "newton per square meter" is also a pressure that is called pascal (Pa). Here is a fine pressure converter: Scroll down to related links and look at "Conversion of pressure or stress units".
daN (dekanewtons) and psi (pounds-force per square inch) are not compatible.
This is like trying to convert meters to hours, it just doesn't work.

1 psi = 64984.65 Pa Therefore 50 MPa = 769 Psi

Multiply by 2.03625437 to convert from psi to inches mercury. Multiply by 0.49109777 to convert from inches mercury to psi.
to convert watts into meters
1psi = 0.068 atm. So to convert 30 psi using dimensional analysis... 30 psi x 0.068 atm/1 psi = 2.04 atm
psi x 6,895 equals newtons per square meter (N/m2)
1 bar = 14.5 PSI
110 - 130 Scfn is what in psi
1 kg = 2.2 pounds 1 cm = 0.39 inch so 1 kg/cm2 = 2.2/(0.39)^2 psi = 14.2 psi
1 psi = 64984.65 Pa Therefore 50 MPa = 769 Psi
1 kilonewton = 1,000 newtons: kilonewtons x 1,000 = newtons
(1 kPa = 0.145038 psi). So, 220 kPa x 0.145038 = 31.9083 psi
Multiply psi x 0.07 to get atmospheres.
Divide by 14.223. Or multiply by 0.07031. Your choice.
Newton is unit of force and psi is unit of pressure, so you cannot convert them.
1 psi = 0.068947572932 bar http://online.unitconverterpro.com/unit-conversion/convert-alpha/pressure.html Eric Serdahl
