A square kilometer (symbol: sq km or km2) is equal to one million square meters. One square kilometer is approximately 0.39 square miles. Large areas of land are expressed in square kilometer -- for example area of a city or a forest.
A square nanometer (symbol: sq nm or nm2) is a unit for measuring area. One is square nanometer is equal to the are of a square with all sides of one nanometer. One nanometer equals to one billionth (short scale) of a meter i.e. 0.000000001 m. One nanometer can be expressed in scientific notation as 1×10−9 m, and as 1/1000000000 meters.
Square nanometer is often used to express area at atomic levels.
