Square meter (m²) - SI unit of area
Square meter is the SI unit of area equal to the area of a square with sides of 1 meter. Used worldwide for measuring floor space, land parcels, and surface areas in science and engineering.
- Symbol: m²
- System: SI derived unit
- Exact relations: 1 m² = 10,000 cm² = 1,000,000 mm² = 1×10⁻⁴ ha
- Imperial/US equivalents: 1 m² ≈ 10.7639104 ft² ≈ 1.19599005 yd² ≈ 1550.0031 in²
- Typical examples: apartment room sizes, building floor plans, material coverage (paint, flooring), cross-sectional and surface areas in calculations
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
