  3. Vickers hardness test - Wikipedia

    en.wikipedia.org/wiki/Vickers_hardness_test

    In the above equation, F could be in N and d in mm, giving HV in the SI unit of MPa. To calculate Vickers hardness number (VHN) using SI units one needs to convert the force applied from newtons to kilogram-force by dividing by 9.806 65 (standard gravity). This leads to the following equation: [4]

  4. Specific strength - Wikipedia

    en.wikipedia.org/wiki/Specific_strength

    The SI unit for specific strength is Pa⋅m 3 /kg, or N⋅m/kg, which is dimensionally equivalent to m 2 /s 2, though the latter form is rarely used. Specific strength has the same units as specific energy , and is related to the maximum specific energy of rotation that an object can have without flying apart due to centrifugal force .

    The SI unit, pascal, is sometimes used instead: 1 kg f ⋅mm −2 = 9.80665 MPa. The test was developed by Frederick Knoop [ 2 ] and colleagues at the National Bureau of Standards (now NIST ) of the United States in 1939, and is defined by the ASTM E384 standard.

  8. Brinell hardness test - Wikipedia

    en.wikipedia.org/wiki/Brinell_hardness_test

    Brinell hardness is sometimes quoted in megapascals; the Brinell hardness number is multiplied by the acceleration due to gravity, 9.80665 m/s 2, to convert it to megapascals. The Brinell hardness number can be correlated with the ultimate tensile strength (UTS), although the relationship is dependent on the material, and therefore determined ...

    For some usage examples, consider the conversion of 1 SCCM to kg/s of a gas of molecular weight , where is in kg/kmol. Furthermore, consider standard conditions of 101325 Pa and 273.15 K, and assume the gas is an ideal gas (i.e., Z n = 1 {\\displaystyle Z_{n}=1} ).
