These are called derived units. In the SI system (or metric system), there are base units for length, mass and time, among others. These are:
The unit of acceleration is expressed as m/s2. An example of a derived unit is the unit of force called the newton (N). Force is equal to mass multiplied by acceleration. Therefore:
force = mass × acceleration
N = kg·m/s2
The units that are Obtained by combining other units is called Derived Units.
Density
A calculated measurement is a measurement obtained by using mathematics rather than physically measuring something. An example would be using the Pythagorean Theorem to calculate the measurement of the hypotenuse of a right triangle based on the lengths of the other two sides. A calculated answer is an answer carefully thought out in advance in response to a question. It is the opposite of a spontaneous answer given without forethought.
you will use cm because it is useful then the other types of measurement
newtons is a measurement of weight where as meters is a measurement of length they can not be measured into each other in other words the porblem is impossible to find an answer to

In science, measurement is the process of obtaining the magnitude of a quantity, such as length or mass, relative to a unit of measurement, such as a meter or a kilogram. A measurement answers the general question, "how many?", as in how manymiles, or millimeters, or gigahertz. As measurement is basically about counting, measurement is conducted in numbers and is quantitative, in comparison to other observations which may be made in words and are qualitative. The term measurement can also be used to refer to a specific result obtained from the measurement process.

The result of combining different metals is an alloy.
Because gold is an element a pure substance cannot be created by combining other elements
by combining them with other metals
By combining or mixing elements
The measurement from one end of an object to the other end of the object is called the length of the object.
A metalloid :)
