Abstract
This paper aimed at investigating and presenting various formulas for the local gravity calculation. The studying of four selected formulas was at parallel latitude of 18๐39’43’’ N and elevation of 300 meters above MSL. The study revealed that, by using these formulas, the locally obtained gravity was very slightly different. The result was 9.784 70 ± 0.000 02 m/s2 or 9.784 70 m/s2 ± 0.002%. The errors of the local gravity calculations, using these formulas, with respected to the mean value were approximately 0.0002%.
