  2. Wilks coefficient - Wikipedia

    en.wikipedia.org/wiki/Wilks_Coefficient

    In this way, the Wilks Coefficient places a greater emphasis on absolute strength, rather than ranking lifters solely based on the relative strength of the lifter compared to body-weight. This creates an even playing field between light and heavyweight lifters—the lighter lifters tend to have a higher relative strength level in comparison to ...

    The VPAM scale as of 2009 runs from 1 to 14, with 1-5 being soft armor, and 6-14 being hard armor. [1] Tested armor must withstand three hits, spaced 120 mm (4.7 inches) apart, of the designated test threat with no more than 25 mm (0.98 inches) of back-face deformation in order to pass.

    To help compare different orders of magnitude, this section lists lengths between 10 −7 and 10 −6 m (100 nm and 1 μm). 100 nm – greatest particle size that can fit through a surgical mask [79] 100 nm – 90% of particles in wood smoke are smaller than this. [citation needed] 120 nm – greatest particle size that can fit through a ULPA ...

    en.wikipedia.org/wiki/List_of_metric_units

    Metric units are units based on the metre, gram or second and decimal (power of ten) multiples or sub-multiples of these. According to Schadow and McDonald, [1] metric units, in general, are those units "defined 'in the spirit' of the metric system, that emerged in late 18th century France and was rapidly adopted by scientists and engineers.
