Convert mmHg to SI units as follows: 1 mmHg = 0.133 32 kPa. Hence the normal blood pressure in SI units is less than 16.0 kPa SBP and less than 10.7 kPa DBP. These values are similar to the pressure of water column of average human height; so pressure has to be measured on arm roughly at the level of the heart.
The conversion in SI units is 1 ksi = 6.895 MPa, or 1 MPa = 0.145 ksi. The megapound per square inch (Mpsi) is another multiple equal to a million psi. It is used in mechanics for the elastic modulus of materials, especially for metals. [5] The conversion in SI units is 1 Mpsi = 6.895 GPa, or 1 GPa = 0.145 Mpsi.
To convert the Vickers hardness number to SI units the hardness number in kilograms-force per square millimeter (kgf/mm 2) has to be multiplied with the standard gravity, , to get the hardness in MPa (N/mm 2) and furthermore divided by 1000 to get the hardness in GPa.
427 ± 15 GPa [7] (predicted) Water: 2.2 GPa (0.32 Mpsi) (value increases at higher pressures) Methanol 823 MPa (at 20 °C and 1 Atm) Solid helium: 50 MPa (approximate) Air 142 kPa (adiabatic bulk modulus [or isentropic bulk modulus]) Air 101 kPa (isothermal bulk modulus) Spacetime: 4.5 × 10 31 Pa (for typical gravitational wave frequencies of ...
Percy Williams Bridgman received a Nobel Prize in 1946 for advancing this area of physics by two magnitudes of pressure (400 MPa to 40 GPa). The list of founding fathers of this field includes also the names of Harry George Drickamer, Tracy Hall, Francis P. Bundy, Leonid F. Vereschagin [], and Sergey M. Stishov [].
From January 2008 to December 2012, if you bought shares in companies when Hector Garcia-Molina joined the board, and sold them when he left, you would have a 47.8 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
The first nanotube ropes (20 mm long) whose tensile strength was published (in 2000) had a strength of 3.6 GPa, still well below their theoretical limit. [41] The density is different depending on the manufacturing method, and the lowest value is 0.037 or 0.55 (solid). [37]
