Square decimeter (dm²) - small metric area
Square decimeter is a metric unit of area equal to the area of a square with sides of 1 decimeter (0.1 meter). Used for small surface areas in product labeling, tiling, and heat-flux specifications.
- Symbol: dm²
- System: SI derived unit
- Exact relations: 1 dm² = (0.1 m)² = 0.01 m² = 100 cm² = 10,000 mm²
- Imperial/US equivalents: 1 dm² ≈ 0.107639 ft² ≈ 0.011959 yd² ≈ 15.5000 in²
- Typical examples: a 10 cm × 10 cm tile = 1 dm²; packaging surface area; heat flux quoted in W/dm²
Arpent (arpent carré) - historical French/Canadian land area
Arpent is a traditional land-area unit from French measure, with region-dependent definitions; in Québec and Louisiana it commonly refers to the “square arpent.” Used historically in cadastral records, land grants, and property descriptions, and still encountered in legal and surveying contexts.
- Names/aliases: arpent, arpent carré (square arpent); related linear unit: arpent (length)
- System: Historical French/Canadian (and Louisiana) customary, non-SI
- Québec (modern metric): 1 arpent (length) ≈ 58.47 m; 1 square arpent ≈ 3,418.9 m² ≈ 0.34189 ha ≈ 0.845 acres
- Louisiana usage: “superficial arpent” for area; commonly treated ≈ 0.846 acres (≈ 3,424 m²), varies by historical source
- Notes: Values differed by locale and era (Paris vs. provincial measures). Always verify the jurisdiction’s legal definition for archival deeds and surveys.
- Typical examples: long-lot riverfront concessions described in arpents (e.g., frontage in linear arpents; parcel area in square arpents)
