There are six JavaScript calculators designed to ease the burden on 2300's referees and players when dealing with "complicated stuff". One covers star and planet orbits, another planet and satellite orbits. The third calculates rotational habitat figures and the fourth takes the hard work out of calculating stutterwarp maths for ships whose mass varies with time. Finally, there are calculators for working out crater impact sizes and the storage capacity of flywheel energy storage devices.
