Earth's gravity number
WebFrom Newton's second law of motion, F=ma, you get that mg=GmM/R^2, where M is the Earth's mass and R is the Earth's radius. Do a little algebra, and you get that M=gR^2/G. g is measured, and so is R. All you need is G (and love). WebThe most recent Earth reference ellipsoid is GRS80, or Geodetic Reference System 1980, which the Global Positioning system uses as its reference. Its geometric parameters are: semi-major axis a = 6378137.0 m, and flattening f = 1/298.257222101.
