A rock's hardness is usually measured in compressive fracture strength rather than a Mohs hardness which measures a mineral's relative hardness in comparison to other minerals. ASTM standard tests have rated gneiss at 50-200 MPa (roughly 350-1400 psi), a range lower than slate, quartzite, or basalt.
The psi of the outer core is the rounding core actullay know as inside.
What is the minimum amount of PSI you can have in your oxygen tank before you need to exchange tanks
PSI
It is 32.12 psi and 1013.2 millibars.
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.
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)
It is 217.556607 pounds per square inch.
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
