In astronomy, the hour angle or right ascension of a star is measured not in degrees, but in hours, minutes and seconds, "time units". Without going into details regarding the celestial coordinate system (namely, the equatorial coordinate system), we note that it is possible to go from degrees to hourly measure and vice versa, using the fact that the rotation of the Earth by 360 ° occurs in one day, i.e. in 24 hours

Thus, we obtain the relations

Hour measure | Degree measure |
---|---|

1 day (24 hours) | 360° |

1 hour | 15° |

1 minute | 0°15' |

1 second | 0°0'15'' |
