Pyeong (평; pyŏng/pyong) - Korean unit of area
Pyeong is a traditional Korean unit of area still common in real-estate listings, though officially replaced by square meters. Used to describe apartment and room sizes, with informal conversions widely understood.
- Names/aliases: pyeong, pyong, 평
- System: Traditional Korean (non-SI)
- Metric equivalent: 1 pyeong = 3.305785 m² (commonly rounded to 3.306 m²)
- Imperial/US equivalent: 1 pyeong ≈ 35.583175 ft²
- Larger units: 1 jeongbo = 3,000 pyeong ≈ 9,917.355 m² ≈ 0.9917355 h
- Typical examples: “25 pyeong” apartment ≈ 82.6 m² (marketing area); room sizes expressed in pyeong for quick mental estimates
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
