There are five different coordinate systems in astronomy. Some of
them have variants, which are all included in this conversion programme.
If you are doing this for the first time, please read instructions (via
links in the form) before you begin.
To make your conversion, please fill in appropriate information below -
both INPUT and OUTPUT parameters of coordinate systems you are interested
in. If you need output coordinates in several systems, make sure to fill in
all required values. Naturally you can only select one INPUT coordinate
system.
In order to serve astronomical community and general public the best
I wish everybody informs me of all malfunctions of this conversion
system, erroneous results, inaccuracies, and other oddities encountered
while making or trying to make a coordinate conversion. Thank you!
