Square Millimeter
A square millimeter (mm²) is a unit of area equal to the area of a square with sides measuring one millimeter.
History/Origin
The square millimeter has been used in scientific and engineering contexts for precise measurement of small areas, especially in fields like electronics and material science, as a subdivision of the metric system established in the 19th century.
Current Use
It is commonly used today in fields such as electronics, manufacturing, and scientific research to measure small surface areas, including the cross-sectional areas of wires and components.
Square Hectometer
A square hectometer (hm^2) is a unit of area equal to the area of a square with sides of one hectometer (100 meters).
History/Origin
The square hectometer originated from the metric system's adoption, where 'hecto' denotes a factor of 100. It has been used primarily in scientific and geographical contexts to measure large areas.
Current Use
The square hectometer is rarely used in everyday measurements but is occasionally employed in scientific, environmental, and geographical studies to express large land or area measurements.
