because most objects viewed are so small that millimeters are to big to measure with.
A decimeter is 100mm, about 4 inches, so it is a unit comfortable for measuring objects in that range or a few times that. It is quite a valid unit, but is seldom used, for most folk find metres, millimetres and centimetres useful enough. As to objects of that dimension order, leaves, books, shoes, small animals and so on.
Measurement is different objects you can measure for example you could measure a road. What would you use? millimetres, centimetres, metres or kilometres? I would choose kilometres because if you used millimetres it would take a long time to measure. Measurement is just mostly about measuring but you have to use all the skills you have like Addition, Subtraction, Multiplication and Division. Things that go into measurement that I know are: Area Perimeter Volume and Angles

objects sink because they are to heavy.
They are sets of objects.
your finger nail can be measured in millimeters
There are lots of units that are used. Typically, nanometres are used for optical wavelengths,micrometres for precision engineering, small cells,millimetres and centimetres in daily use for small lengths,metres for objects that are larger - roughly bigger than the height of an adult,kilometres for distances within town and between towns,astronomical units, light years or parsecs for interstellar (and inter galactic) distances.In most cases there are equivalent units in the near-obsolete Imperial system.
1 metre = 100 centimetres = 1,000 millimetres
Either a radio galaxy or a quasar
If you were looking at something small, it is more meaningful to say this is 20 microns long, instead of 0.02mm. When you talk about decimal places, it is harder to grasp the figure as quickly as people often working with microns grasp the relevance of 20micron. Such samples include fiber size, transsectional areas taken for cell viewing through a light microscope (using a microtome, you get a nice cut), etc.
Length, as with any measurement of distance in the metric system, is measured in metres (m) 1 metre is approximately 3.3 feet in length. From an engineering perspective millimetres (1/1000th of a metre) are more commonly used to avoid having to quote lengths to 2 decimal places.The basic unit of length is the meter.
Any linear measurement could be used to describe an object's length. Miles, Yards, feet and inches. Kilometres, metres, centimetres and millimetres.
Interference patterns created by the interaction of the two beams of light are recorded. These patterns can provide information about the properties of the light waves and the objects they interact with.

Diameter is the value used to rate things such as balls, bullets, and other round objects. So an 8mm ball has a diameter of 8 millimetres.
a list is a collection of objects, usually with some common characteristic or purpose, recorded in sequence. the sequence may or may not have an order.
