4.2 Units in SQL tables

In the gama-local SQLite database, distances are given in meters and their standard deviations (rms errors) in millimeters. Angular values are given in radians as well as their standard deviations.

Conversions between radians, gons and degrees:

 
    rad = gon * pi / 200
    rad = deg * pi / 180
    gon = rad * 200 / pi
    deg = rad * 180 / pi
