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.


Square Centimeter [cm²]


A square centimeter (cm²) is a unit of area that represents a square with sides 1 centimeter long. It is used to measure small surfaces like paper, labels, or tiny objects.

1 cm² = 0.0001 m².
