Ellipsoid GRS 80

Computed values

Use the radians function to enter angles in ddd.mmssssss... format. For example, a latitude of 41°15'18.2106" N is entered as f:=radian(41,15,18.2106). Enter southern latitudes and western longitudes as negative values. A latitude of 41°15'18.2106 S is entered as f:=radian(-41,15,18.2106).
