A bolt with property class 12.9 has a tensile strength of 1200 MPa (1 MPa = 1 N/mm 2) or 1.2 kN/mm 2 and the yield strength is 0.90 times tensile strength, 1080 MPa in this case. A bolt with property class 4.6 has a tensile strength of 400 MPa (1 MPa = 1 N/mm 2 ) or 0.4 kN/mm 2 and yield strength is 0.60 times tensile strength, 240 MPa in this ...

is the static pressure [M 1 L −1 T −2], is the specific gas constant [L 2 T −2 θ −1] (287.05 J/(kg K) for air), is the density [M 1 L −3]. If the temperature is increased, but the volume kept constant, then the Knudsen number (and the mean free path) doesn't change (for an ideal gas). In this case, the density stays the same.
In engineering and physics, g c is a unit conversion factor used to convert mass to force or vice versa. [1] It is defined as = In unit systems where force is a derived unit, like in SI units, g c is equal to 1.
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 .

Where t is the solidification time, V is the volume of the casting, A is the surface area of the casting that contacts the mold, n is a constant, [clarification needed] and B is the mold constant. This relationship can be expressed more simply as: = Where the modulus M is the ratio of the casting's volume to its surface area:
