The angle may be measured in degrees or in time, with 24 h = 360° exactly. In celestial navigation, the convention is to measure in degrees westward from the prime meridian (Greenwich hour angle, GHA), from the local meridian (local hour angle, LHA) or from the first point of Aries (sidereal hour angle, SHA).
The length of the SI second was calibrated on the basis of the second of ephemeris time [29] [32] and can now be seen to have a relationship with the mean solar day observed between 1750 and 1892, analysed by Simon Newcomb. As a result, the SI second is close to 1 / 86400 of a mean solar day in the mid‑19th century. [44]
