# Convert Right Ascension To Degrees

### 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.

The right ascension is the angle between an object and the location of the vernal equinox First Point in Aries measured eastward along the celestial equator in hours minutes and seconds of sidereal time. Since the location of the vernal equinox changes due to the precession of the Earth s axis of rotation coordinates must be given with reference to a date or epoch.
