What lengths are most conveniently measured in astronomical units?
Stellar distances, like the distances of stars and galaxies from Earth
Will astronomers measure all the distances of 100 billion galaxies in the observable universe?
Someday astronomers may have measured all the distances of 100 billion galaxies in the observable universe.
How do distances between planets solar systems galaxies and the universe compare?
The distance between planets are measured in millions of kilometers while the distance between solar systems are measured in light years while the galxies and the universe are measured in AU (astronautical units)
Where is the distance from canberra measured from?
distances between cities are usually measured from the central post offices
What could be measured in kilometers?
Distances between towns is one possibility.
How do you measure all the distances of the 100 billion galaxies in the universe?
I think it's currently impossible to do that - specifically, to measure the distances of ALL the galaxies. There are just too many Astronomers might take a small section of the sky - say, a square degree or even a fraction thereof, analyze the galaxies in such a section, and extrapolate. As to the measurement itself, there are different methods; the Wikipedia article on "cosmic distance ladder" can give you a general idea. In summary, the farthest galaxies are simply measured by their redshift. That is to say, the farther they are, the faster they move away from us; and this can be measured using the Doppler effect.
What shows the relationship between distances on a map and the corresponding distances on earth surfaces?
The SCALE of the map indicates the relationship between lengths measured on a map and the actual distances. It can indicate the ratio of distances (e.g. 1:10000) or the equivalent actual distance for an inch or centimeter as measured on the map, often providing a measurement bar for various distances.

The size of galaxies are measured in?
They are measured in light years. Galaxies are often 100,000 light years across or more.
What units are stellar distances expressed in?
Stellar distances are measured in light-years, which is the average distance between the Earth and the Sun.
When do scientist use light-years?
That is usually measured for large distances, such as the distance to other stars, or even to other galaxies. Another unit, the "parsec", is also common in this case.
