The corresponding values for Earth are currently 23 h 56 m 4.0916 s and 24 h 00 m 00.002 s, respectively, which yields a conversion factor of 1.027 491 2517 Earth days/sol: thus, Mars's solar day is only about 2.75% longer than Earth's; approximately 73 sols pass for every 75 Earth days.
Sol (borrowed from the Latin word for sun) is a solar day on Mars; that is, a Mars-day. A sol is the apparent interval between two successive returns of the Sun to the same meridian (sundial time) as seen by an observer on Mars. It is one of several units for timekeeping on Mars. A sol is slightly longer than an Earth day.

A single official calendar for Mars does not yet exist, so a numbered Mars day, known as a "Sol", is used in the calculation. NASA or another authoritative agency determines the Sol number for the new event on Mars by counting Sols from the beginning of the mission. The Mars clock time of the event is determined by geographic location and sun ...
Factor () Multiple Value Item 0 0 0 Singularity: 10 −35: 1 Planck length: 0.0000162 qm Planck length; typical scale of hypothetical loop quantum gravity or size of a hypothetical string and of branes; according to string theory, lengths smaller than this do not make any physical sense. [1]
gives 4398 sols since the Mars Science Laboratory landed on Mars; This template was created for use on Mars mission pages, NASA ones in particular, which identify mission milestones based on the mission sol which begins with sol 0 on the landing date for rover and landers and the orbital insertion date for orbiters.
Along with hitting a record-setting altitude of 40 feet, the helicopter clocked its first mile on its 152nd sol (Mars day) after landing with Perseverance in February. Tweet may ha.
Both of these factor in what astronomical objects you can see from surface telescopes (time of year) and when you can best see them (time of day), but neither are in unit correspondence. For simplicity, the explanations given assume a degree/day in the Earth's annual rotation around the Sun, which is off by roughly 1%.
