Units such as light years and astronomical units are useful because they can be used to measure very large distances without yielding extremely large numbers.
gram, kilogram. It really depends on the object whose mass is being measured. But since nanograms to tons are all related by simple multiples of 10, it does not matter a great deal which one is chosen.
All of them. They are all measurement units counted in divisions or multiples of 10.
It is sometimes useful to use arbitrary units because it may take you too much time to figure out the logically ideal units to use, or you may not even know in which numerical range your results may fall.
The US monetary system is not in metric units. Instead, it uses a system based on the decimal system, where units are related to each other by powers of 10. For example, there are 10 dimes in a dollar, 100 cents in a dollar, and so on.
The SI (Systeme International) units for mass is the kilogram. For length, it is the Metre, and for volume, the Litre. Note the system is known as the International System, (SI). The International Bureau for Weights and Measures is located near Paris France, the on their web site they have lots of useful information, including for example, the prefixes for the multiples and sub-multiples. Such as Mega, and micro.
The units digits start with 8 and go down in steps of 2. The units digit repeats every 5 multiples, The last pair of digits repeat every 25 multiples.
Units of measurement provide a standard to measure mass, length etc.So, it is useful.
