Lightyears. The distance between the Sun and Earth is 1.49 lightyears (149 000 000 km)
distances between cities are usually measured from the central post offices
That is usually measured in degrees.
usually the space is measured in light years
Cities have GPS coordinates for their geographic centers. Distances are usually measured betweem them.
Miles in the US. Kilometers in most other places. Or, distance is often measured in time: How many hours or minutes does it take to get there.
Usually in kilometers. Larger objects, such as galaxies, may be measured in light-years, or in parsec.
The wavelength (denoted by Greek letter Lambda) is the minimum distance between any two corresponding points on a wave that are in the same stage of the cycle. This distance is usually measured from peak to peak (crest to crest or trough to trough). Wavelength is a distance and is usually measured in meters.

usually by AU(astronomical unit). it's the average distance between Earth and Sun. Sometimes kilometers or miles are used for public.
