About these units
Sabin (sabin)
A sabin is the acoustic unit of sound absorption area, equivalent to the absorption provided by one square foot of a perfectly absorbing surface. Unlike geometric area units, the sabin measures how much sound energy a surface absorbs rather than its physical size alone. Materials with partial absorption effectiveness—such as acoustic tiles or drapes—contribute fractional sabins depending on their absorption coefficient. Architects and acoustic engineers use sabins to design theaters, concert halls, classrooms, and workplaces. The unit translates directly into reverberation time calculations, making it a foundational concept in architectural acoustics.
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.
