Square Kilometer
A square kilometer is a unit of area equal to the area of a square with sides measuring one kilometer each.
History/Origin
The square kilometer has been used as a standard unit of area measurement in the metric system since its adoption, primarily for measuring large land areas such as countries and regions.
Current Use
It is commonly used in geography, urban planning, and environmental studies to quantify land and area sizes, especially in contexts requiring large-scale measurements.
Square Nanometer
A square nanometer (nm^2) is a unit of area equal to the area of a square with sides measuring one nanometer each.
History/Origin
The nanometer as a unit of length has been used since the development of nanotechnology in the late 20th century, with the concept of measuring extremely small areas like nm^2 emerging alongside advancements in microscopy and nanoscience.
Current Use
Square nanometers are primarily used in nanotechnology, materials science, and semiconductor industries to quantify extremely small surface areas, such as the dimensions of nanomaterials, thin films, and microscopic structures.
