What are Square Micrometers?
Square micrometers, also known as square microns, are a unit of area in the metric system. One square micrometer is and area equivelent to a square of one micrometer on each side, equal to one millionth of a square meter. This tiny unit of measurement is often used to describe the area of very small objects, such as microorganisms or nanoparticles. To put it into perspective, a single human hair is about 50-100 micrometers in diameter, so a square micrometer is incredibly small in comparison.
What are Square Kilometers?
Square kilometers are units of area measurement in the metric system. A square kilometer is a unit of area equal to 1,000,000 square meters, or the area of a square with sides that are each 1 kilometer long. It is commonly used to measure large areas of land, such as countries or continents. For example, the total land area of Australia is approximately 7.7 million square kilometers.
