About these units
Square Dekameter (dam²)
A square dekameter equals 100 square meters and is used in agriculture, sports field planning, and land measurement in some metric-oriented countries. It is particularly useful for measuring the footprint of small buildings, gardens, or sport courts. Landscape architects and civil engineers may express project areas in dam² when m² values become too large and hectares too large-scale. Although not as common as the square meter or hectare, the dam² exemplifies the flexibility of the metric system for scaling area units to suit practical needs.
Circular Mil (circ mil)
A circular mil is defined as the area of a circle with a diameter of exactly one mil. Because wires and cables have circular cross-sections, the circular mil has become a standard unit in electrical engineering for specifying conductor sizes. One circular mil simplifies calculations because area scales directly with the square of wire diameter without needing π in computations. For example, doubling a wire's diameter increases its circular-mil area fourfold. This makes circular mils extremely convenient for determining ampacity, resistance, and voltage drop in electrical conductors. Even though SI units are common elsewhere, the circular mil remains entrenched in North American electrical codes.
