  2. Specific surface area - Wikipedia

    en.wikipedia.org/wiki/Specific_surface_area

    Ceramic Raschig rings.....and plastic BiaƂecki rings of increased SSA. Values obtained for specific surface area depend on the method of measurement. In adsorption based methods, the size of the adsorbate molecule (the probe molecule), the exposed crystallographic planes at the surface and measurement temperature all affect the obtained specific surface area.

  3. Floor area - Wikipedia

    en.wikipedia.org/wiki/Floor_area

    In architecture, construction, and real estate, floor area, floor space, or floorspace is the area (measured in square metres or square feet) taken up by a building or part of it. The ways of defining "floor area" depend on what factors of the building should or should not be included, such as external walls, internal walls, corridors, lift ...

  4. American Measurement Standard - Wikipedia

    en.wikipedia.org/wiki/American_Measurement_Standard

    The methodology of the American Measurement Standard was compiled and edited by a consensus of real estate professionals including real estate agents, appraisers, assessors, home builders and architects, and is based on the exterior dimensions of a dwelling. The AMS contains over three times more specific home measurement details than any other ...

  5. Floor plan - Wikipedia

    en.wikipedia.org/wiki/Floor_plan

    A floor plan is not a top view or bird's-eye view; it is a measured drawing to scale of the layout of a floor in a building. A top view or bird's-eye view does not show an orthogonally projected plane cut at the typical four foot height above the floor level. A floor plan may show any of the following elements: [3] interior walls and hallways ...

  6. Floor area ratio - Wikipedia

    en.wikipedia.org/wiki/Floor_area_ratio

    Floor Area ratio is sometimes called floor space ratio (FSR), floor space index (FSI), site ratio or plot ratio. The difference between FAR and FSI is that the first is a ratio, while the latter is an index. Index numbers are values expressed as a percentage of a single base figure. Thus an FAR of 1.5 is translated as an FSI of 150%.

  7. M squared - Wikipedia

    en.wikipedia.org/wiki/M_squared

    When measuring the beam parameter product and M 2, one uses the D4σ or "second moment" width of the beam to determine both the radius of the beam's waist and the divergence in the far field. [ 1 ] M 2 can be measured by placing an array detector or scanning-slit profiler at multiple positions within the beam after focusing it with a lens of ...

  8. Area density - Wikipedia

    en.wikipedia.org/wiki/Area_density

    A special type of area density is called column density (also columnar mass density or simply column density), denoted ρ A or σ.It is the mass of substance per unit area integrated along a path; [1] It is obtained integrating volumetric density over a column: [2] =.

  9. Pyeong - Wikipedia

    en.wikipedia.org/wiki/Pyeong

    It is the standard traditional measure for real estate floorspace, with an average house reckoned as about 25 pyeong, a studio apartment as 8–12 py, and a garret as 1½ py. In South Korea , the unit has been officially banned since 1961 but with little effect prior to the criminalization of its commercial use effective 1 July 2007. [ 3 ]
