centimeters
There is no such unit of measurement as a diameter, a diameter is the length across something. Perhaps you are thinking of a decimetre.
Whether you are finding the area of a circle or the area of a square or any other geometrical shape, it is always the case that to go from a linear measurement (a radius, a side, or whatever) to a surface area requires you to use a square of the linear measurement; you are increasing size in two dimensions, length and width, and therefore the effect is the increase the area exponentially, not linearly.
nm. A nanometer represents 10 ^ -9 or one billionth of a meter.
cubic feet or cubic inches
It is cubic units
kilobytes

The smallest unit of measurement used to describe the storage capacity of a computer is called a bit. It is a binary digit that can represent either a 0 or a 1, and is the basic building block of all digital data.

You would use millimeters for the measure of the capacity of a paper cup.
The capacity of a bathtub could be appropriately measured in liters.
