^{}### How to Calculate Longitude from Right Ascension Sciencing

For example a right ascension of 13 hours in decimal form is 13.0 and multiplying this by 15 degrees gives 195 degrees. This value is greater than 180 degrees so subtract 360 from it as follows 195-360 -165. The coordinate in longitude is -156 degrees and it is referencing a location west of Greenwich.

^{}### How can I convert Right Ascension and declination to

Right Ascension and declination are angular measures RA 15 gives degrees c. Basically RA is where the siderial zenith is at any time declination is the distance from the zodiac. You multiply RA by 15 and get angles.
