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 micrometer (symbol: sq μm or μm2) is a unit for measuring area. One is square micrometer is equal to the area of a square with all sides of one micrometer. One micrometer is one millionth of a meter (or one thousandth of a millimeter, 0.001 mm, or about 0.00004 inch). One micrometer can be expressed in scientific notation as 1×10−6 m.
