The distance around a circle is its circumference and it can be measured in any linear units.
Scientists measure distances around a circle using radians or degrees. Radians are the preferred unit because they provide a more direct relationship to the radius of the circle. One complete revolution around a circle is equivalent to 2π radians or 360 degrees.
No, a second is a unit of time, not a unit of distance. It is used to measure time intervals, not distances. Distances are typically measured in units such as meters, kilometers, or miles.
You would typically measure the distance around a school in meters, as this is a more precise unit of measurement for shorter distances. Kilometers are better suited for measuring longer distances.
Light years or parsecs
The unit used to measure distances from one point to another is typically meters (m) or kilometers (km) for longer distances. Other common units include centimeters (cm) for smaller distances and miles (mi) for distances in the United States.

a Lightyear, around 1013 kilometres.
you would measure distances in centimetres, metres and kilo metres.
A circle can have a unit of length which could be either a measure of its diameter or radius, or of its circumference. Or the circle could have the unit of area.
AU is not used to measure the distances on earth, because a astronomical unit is a unit of measurement equal to the distance between Earth and Sun. So that's why you cannot use Au for measure the distances on Earth.
It depends on what you are trying to measure. Long distances usually are measured in miles. Survey distances usually are measured in feet.

To measure the distance of stars you have to measure by light years.
A unit circle is not normally called 2 pi. Because the radius length measure of the unit circle is 1 unit, then the circumference of a unit circle is 2*pi, and its area is pi.
The unit of radius used to measure the size of a circle is typically in units of length, such as inches, centimeters, or meters.
