Its 87.02262 psi
1 psi = 6.89476 kPa (rounded) 1 kPa = 0.14504 psi (rounded) 1 mPa = 1,000 kPa
1000 psi is 6.895 MPa (mega pascals) where a Pa is 1 Newton/m2; thos 30 psi = 30/1000 x 6895000 = 206,850 N/m2
Depends on the concrete An empirical equation is 4500*sqrt(R) where R is the nominal compression resistance (usually 30 MPa) R needs to be expressed in MPa in this equation
Multiply psi x 0.07 to get atmospheres.
E=2800 MPa nu=0.38 For Perspex sheet
1 psi = 6.89476 kPa (rounded) 1 kPa = 0.14504 psi (rounded) 1 mPa = 1,000 kPa
1 psi = 64984.65 Pa Therefore 50 MPa = 769 Psi
1 MPa = 145.038 PSI.
300 mpa
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
bar x 14.503773773 = psi 1.5 bar x 14.503773773 = 21.76 psi (rounded)
MPa stands for Megapascal, a unit of pressure. 1 Mpa is equal to 145.0377 psi
MPa x 145 = psi
Commercial grade Titanium (92% pure) is 63,000 psi (434 MPa). Certain titanium alloys (e.g., Beta C) achieve tensile strengths of over 200,000 psi (1,400 MPa). Megapascal or MPa is a unit to measure tensile strength.
1 psi = 0.00689475728 MPaAs such the average strength in PSI = (4620 + 4580 + 4400 + 4460 + 4200) / 5= 4452 psiAverage strength in MPa = 4452 x 0.00689475728= 30.69545941056 MPa= 30.7 MPa
Divide by 6.895 and multiply by 1000 to get psi (500/6.895) x 1000 = 72,516 psi
At the least (without special treatmens), use 205 MPa 30,000 psi
