there is track width (measured from mid rail to mid rail) and track gauge (measured from inside rail to inside rail. As that is the most important size of track, that is normally the distances referenced to. normal distance for track gauge is 1435 mm
Any distances between two points outside the solar system, or betweenanything inside the solar system and anything outside it, are.(With the exception of the distances now being estimated between exoplanetsand their respective host-stars.)
road distances are generally measured from town halls. A noticeable exception is 'le point zéro' in Paris, a brass marker just outside Notre-Dame cathedral, from which distances are measured to other French towns.
they are measured in AU
The distances are measured from the tip of home plate to the bottom of the fence.
Usually such distances are measured either in light-years, or in parsecs.
Long distances are measured in AU in Eve Online. For short distances, it is measured in KM.
The brass marker outside Notre Dame de Paris is the official centre of Paris, from which all road distances are measured.
It depends on what you are trying to measure. Long distances usually are measured in miles. Survey distances usually are measured in feet.

No. Short distances (the width of a planet) are measured in kilometers. Distances from one place to another in our solar system are measured in Astronomical Units (AU), one AU being 93 million miles. Longer distances outside our solar system are popularly measured in light years, Alpha Centauri is 4.2 light years away, for example, but note I said "popularly". Astronomers use the term "parsecs" when speaking of interstellar distances (one parsec is 3.26 light years).
Astronomical units (AU) are primarily used to measure distances within our solar system, specifically the distance from Earth to the Sun. Outside the solar system, distances are typically measured in light years or parsecs, depending on the scale.
