Square Decimeter [dm²]

A square decimeter (dm²) is a unit of area equal to a square with sides 1 decimeter (10 centimeters) long.

1 dm² = 0.01 m² = 100 cm².

It is commonly used to measure small surfaces, such as the area of tiles or sheets of paper.

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.
