Abstract
Existing methods for conversion between synodic and sidereal rotation velocities of the Sun are tested for validity using state-of-the-art ephemeris data. We found that some of them agree well with ephemeris calculations while others show a discrepancy of almost 0.01∘ day−1. This discrepancy is attributed to a missing factor and a new corrected relation is given.
