It describes digital factory measuring equipment as similar to a scanner and presents the demonstration video below. The original article identifies the machine as a product of Kardan Machine Manufacturing. It provides no model number, calibration record or numerical accuracy specification.<\/p><h2 class=\"wp-block-heading\">Clarifying \u201cfoot of leather\u201d and square feet<\/h2><p class=\"wp-block-paragraph\">The Persian text gives a historical definition of a leather-trade unit as a square measuring 32.99 \u00d7 32.99 cm, attributing it to a 1919 agreement between Italian and Spanish leather manufacturers. That historical attribution has not been independently verified here. It should not be read as the definition of the international square foot.<\/p><p class=\"wp-block-paragraph\">For standard unit conversion, <strong>1 ft\u00b2 = 0.09290304 m\u00b2 = 929.0304 cm\u00b2<\/strong>, equivalent to a square 30.48 cm on each side. See the <a href=\"https:\/\/www.nist.gov\/pml\/special-publication-811\/nist-guide-si-appendix-b-conversion-factors\/nist-guide-si-appendix-b9\">NIST unit-conversion reference<\/a>. A square of 32.99 \u00d7 32.99 cm instead has an area of about 0.108834 m\u00b2. When comparing a measurement or quotation, ask which unit and conversion factor are being used.<\/p><h2 class=\"wp-block-heading\">Original demonstration video<\/h2><p class=\"wp-block-paragraph\">The video is retained from the Persian source.
