because most objects viewed are so small that millimeters are to big to measure with.

What are examples of units used for length?

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.


What units are used to measure objects smaller than a meter?

1 metre = 100 centimetres = 1,000 millimetres

Why would you use micrometres not millimetres to measure the siz eof objects?

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.


What unit is used to measure length in the metric system?

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.


How wide is 8 mm?

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.


What object is 11 centimeters long?

11 centimetres is the equivilant of: * 4.2 inches * 110 millimetres * 0.11 metres


Which unit of measurement describes an objects length?

Any linear measurement could be used to describe an object's length. Miles, Yards, feet and inches. Kilometres, metres, centimetres and millimetres.


Name objects you can measure with decimeters?

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.


Definition of list?

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.


What customary unit of measure would you use to measure distance?

Depends on the context. Inter city distances in kilometres, distances around the house or garden in metres, smaller objects in centimetres. Scientists or specialists would meause interstellar distances in light years or parsecs, accurate measures of day-to-day objects in millimetres, wavelenth of electromagnetic radiation in nanometres, etc.
