Unit for what? Masses are commonly given in kg., or in multiples of the Earth's mass. Distances are given either in km., or in astronomical units - that is, multiples of the average distance from Sun to Earth.Unit for what?

Use "Astronomical UNit" or AU when discussing distances within the solar system. Use "light year" when talking about the distances between stars.
An Astronomical Unit is the distance between Earth and the Sun and is used as a measurement unit for measuring the distances of other objects from Earth.
. . . . . . . . . .Scientists mainly use Astrological Units [abbre. AU ] to measure distances within the Solar System. 1 Astrological Unit is somewhere around 49,580,000 - 49,590,000 kilometers, or roughly 49,600,000 kilometers if you prefer to round up.- S0L+++AstroNOMICAL, NOT Astrological!Astronomy is the science, using Astronomical Units.Astrology is collective name for an assortment of similar, semi-religious beliefs.. . . . . . . . . .
This unit is mainly used for distances within the Solar System.
1 astronomical unit.
The astronomical unit is the mean distance from Earth to Sun. It is commonly used for distances in the Solar System. This way, it is easier to imagine the distances, since the meter or kilometer are very small units (an astronomical unit is about 150 million km, or 150 billion meters), and the light year and the parsec are very large units (a light-year is about 63,000 astronomical units, the parsec is even larger). Light-minutes or light-hours might be used instead, within the Solar System, but the astronomical unit has become quite popular.
None of them.
The distance light travels in an hour. This unit is not used as frequently as the light-year, for example. Distances within the solar system might be expressed in light-hours, but another unit - the astronomical unit - is more commonly used.
It depends on what you are trying to measure. Long distances usually are measured in miles. Survey distances usually are measured in feet.
AU - Astronomical Unit, but miles and kilometers are used for distances
Not all of them no. Weight can be measures in pounds. Mass can be measured in pounds But astronomical units are a measure of distance so these are not measured in pounds. Finally pounds are a very outmoded unit it. The international standard unit for measuring weight is the Kilogram.
