Circular Inch


A circular inch is a unit of area used primarily in engineering and wire gauge measurements. It represents the area of a circle with a diameter of one inch.



  • Formula: Area = π × (radius)²



  • Since the radius is half an inch,

    Area = π × (0.5 in)² = π × 0.25 in² ≈ 0.7854 square inches (in²).



Circular inches are often used to specify cross-sectional areas of wires or pipes.


Sabin


A sabin is a unit of sound absorption area used in acoustics. It measures how much sound is absorbed by a surface.



  • 1 sabin equals 1 square foot of perfectly absorbing surface (in imperial units) or 1 square meter (in metric units).



  • It helps quantify the acoustic absorption of materials in rooms or auditoriums.



Sabins are important in designing spaces with good sound quality by controlling echoes and reverberation.
