Square Meter [m²]
A square meter (m²) is the SI unit of area. It represents the area of a square with sides that are 1 meter long. Square meters are commonly used to measure spaces like rooms, land, and buildings. For example, a room that is 5 meters long and 4 meters wide has an area of 20 m² (5 × 4 = 20).
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.
