    C p is the correction factor related to the shape of the indenter, ideally 0.070279 P is the load. HK values are typically in the range from 100 to 1000, when specified in the conventional units of kg f ⋅mm −2. The SI unit, pascal, is sometimes used instead: 1 kg f ⋅mm −2 = 9.80665 MPa.

  3. Vickers hardness test - Wikipedia

    en.wikipedia.org/wiki/Vickers_hardness_test

    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.

    en.wikipedia.org/wiki/Template:Convert/list_of_units

    {{Convert}} uses unit-codes, which are similar to, but not necessarily exactly the same as, the usual written abbreviation for a given unit. These unit-codes are displayed in column 3 of the following tables. These are accepted as input by {{convert}} as the second and third unnamed parameters: {{convert|100|kg|lb}} → 100 kilograms (220 lb)

  5. 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 ...

    The work done when a force of one newton moves the point of its application a distance of one metre in the direction of the force. [32] = 1 J = 1 m⋅N = 1 kg⋅m 2 /s 2 = 1 C⋅V = 1 W⋅s kilocalorie; large calorie: kcal; Cal ≡ 1000 cal IT = 4.1868 × 10 3 J: kilowatt-hour; Board of Trade Unit: kW⋅h; B.O.T.U. ≡ 1 kW × 1 h = 3.6 × 10 6 J

  8. Specific weight - Wikipedia

    en.wikipedia.org/wiki/Specific_weight

    The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...

  9. APT (programming language) - Wikipedia

    en.wikipedia.org/wiki/APT_(programming_language)

    APT is used to program numerically-controlled machine tools to create complex parts using a cutting tool moving in space. It is used to calculate a path that a tool must follow to generate a desired form. APT is a special-purpose language and the predecessor to modern computer aided manufacturing (CAM) systems. It was created and refined during ...
