The standard atmosphere was originally defined as the pressure exerted by a 760 mm column of mercury at 0 °C (32 °F) and standard gravity (g n = 9.806 65 m/s 2). [2] It was used as a reference condition for physical and chemical properties, and the definition of the centigrade temperature scale set 100 °C as the boiling point of water at this pressure.
The metre–tonne–second (MTS) system of units was invented in France (hence the derived unit names sthène and pièze) where it became the legal system between 1919 and 1961. [1] It was adopted by the Soviet Union in 1933 and abolished there in 1955.
The word Mach is always capitalized since it derives from a proper name, and since the Mach number is a dimensionless quantity rather than a unit of measure, the number comes after the word Mach. It was also known as Mach's number by Lockheed when reporting the effects of compressibility on the P-38 aircraft in 1942.

EN8 bright has a tensile strength of 800 MPa and mild steel, for comparison, has a tensile strength of 400 MPa. To calculate the force to shear a 25 mm diameter bar of EN8 bright steel; area of the bar in mm 2 = (12.5 2)(π) ≈ 490.8 mm 2 0.8 kN/mm 2 × 490.8 mm 2 = 392.64 kN ≈ 40 tonne-force
A first-order estimate of the relation between ASTM D2240 type D hardness (for a conical indenter with a 15° half-cone angle) and the elastic modulus of the material being tested is [10] = (+ +), where is the ASTM D2240 type D hardness, and is in MPa.
