Square yard (yd²) - Imperial/US area unit
Square yard is an Imperial/US customary unit of area equal to a square 1 yard on a side. Used for land parcels, textiles, and construction takeoffs.
- Symbol: yd²
- System: Imperial/US customary
- Exact relations: 1 yd² = 9 ft² = 1296 in² = (0.9144 m)² = 0.83612736 m² (exact)
- Other relations: 1 m² ≈ 1.19599005 yd²
- Typical examples: fabric sold by the square yard; lawn and paving area estimates; roofing takeoffs
Square millimeter (mm²) - tiny metric area
Square millimeter is a metric unit of area equal to the area of a square with sides of 1 millimeter. Used for tiny surface areas, cross-sections, and component footprints in engineering and electronics.
- Symbol: mm²
- System: SI derived unit
- Exact relations: 1 mm² = (0.001 m)² = 1×10⁻⁶ m² = 0.01 cm²; 100 mm² = 1 cm²
- Imperial/US equivalents: 1 mm² = 1/645.16 in² ≈ 0.0015500031 in² ≈ 0.00001076391 ft² ≈ 0.00000119599 yd²
- Typical examples: wire cross-sectional areas (e.g., 2.5 mm²), microchip die areas, small nozzle or orifice openings
