  2. Turnover number - Wikipedia

    en.wikipedia.org/wiki/Turnover_number

    In chemistry, the term "turnover number" has two distinct meanings.. In enzymology, the turnover number (k cat) is defined as the limiting number of chemical conversions of substrate molecules per second that a single active site will execute for a given enzyme concentration [E T] for enzymes with two or more active sites.

  3. Slug (unit) - Wikipedia

    en.wikipedia.org/wiki/Slug_(unit)

    One slug is a mass equal to 32.17405 lb (14.59390 kg) based on standard gravity, the international foot, and the avoirdupois pound. [3] In other words, at the Earth's surface (in standard gravity), an object with a mass of 1 slug weighs approximately 32.17405 lbf or 143.1173 N. [ 4 ] [ 5 ]

    This translates to a hoppus foot being equal to 1.273 cubic feet (2,200 in 3; 0.0360 m 3). The hoppus board foot, when milled, yields about one board foot. The volume yielded by the quarter-girth formula is 78.54% of cubic measure (i.e. 1 ft 3 = 0.7854 h ft; 1 h ft = 1.273 ft 3). [46]

  5. Foot per second squared - Wikipedia

    en.wikipedia.org/wiki/Foot_per_second_squared

    The foot per second squared (plural feet per second squared) is a unit of acceleration. [1] It expresses change in velocity expressed in units of feet per second (ft/s) divided by time in seconds (s) (or the distance in feet (ft) traveled or displaced, divided by the time in seconds (s) squared).

  6. Reciprocal length - Wikipedia

    en.wikipedia.org/wiki/Reciprocal_length

    Spatial frequency is a reciprocal length, which can thus be used as a measure of energy, usually of a particle. For example, the reciprocal centimetre, cm −1, is an energy unit equal to the energy of a photon with a wavelength of 1 cm. That energy amounts to approximately 1.24 × 10 −4 eV or 1.986 × 10 −23 J.

  7. Foot–pound–second system of units - Wikipedia

    When the pound is used as a unit of mass, the core of the coherent system is similar and functionally equivalent to the corresponding subsets of the International System of Units (SI), using metre, kilogram and second (MKS), and the earlier centimetre–gram–second system of units (CGS).

  9. Katha (unit) - Wikipedia

    en.wikipedia.org/wiki/Katha_(unit)

    In Bihar, one Katha may vary from 720 to 3,267 square feet (ft 2). 1 Bigha = 20 Katha. One katha is divided in 20 dhur. One dhur is subdivided in 20 dhurki. The origin of the term and measurement unit was during the Pala Empire. [1] 1 Decimal = 435.6 square feet & 1 Acre = 100 decimal. [2] [3] In Patna & Arrah, 1 Katha is equal to 1,361.25 ft 2 ...
