WebbSpecific Gravity = = Moreover, the mass of the object is also directly related to the density. In addition, the mass is measured in Newtons. Furthermore, we can also find specific gravity with the weight of the object and water Specific Gravity = = Most noteworthy, in all these formulas all the units are the same and they cancel each other out. WebbThese factors are represented in the following equation, that defines the variation of g with latitude θ g (θ) = 9.78031846 (1+ 0.0053024 sin ² θ – 0.0000058 sin² 2θ) ... All the these equations define the expected value of theoretical gravity (or normal gravity) at latitude θ.

Webb1 feb. 2002 · A simple formula will convert 1967 theoretical (or normal) gravity to the newer more accurate 1980 system, GRS 80 (Chapter II). A number of different procedures can be used to reduce a gravity measurement from the physical surface to sea level and, depending upon which procedure is used, different types of gravity anomalies result. WebbCreate another field called g_t (Float, Precision 12, Scale 6) for the theoretical gravity. Use the field calculator to find theoretical gravity based upon the latitude in radians. Note that the syntax for field calculations can be frustrating, so before you calculate, copy the equation using the "copy" button on your keyboard.

WebbTelford, Geldart and Sheriff (1990) give the theoretical gravity equation for GRS1967, however different sources provide slightly different equations (see list below). There are newer equations for GRS80 and WGS84, as well as the older 1930 equation.
