About Section (section)
Definition
A section is a unit of land area equal to 1 square mile (640 acres or 2.59 km²), used in the US Public Land Survey System.
Mathematical Relationship
1 section = 1 mi² = 640 acres = 2.59 km². 36 sections = 1 township.
Conversion Formula
To convert sections to acres: multiply by 640. To km²: multiply by 2.59.
Practical Applications
Rural property descriptions, agricultural land division, mineral rights, and road grid planning in the western US.
Interesting Facts
Section 16 in every township was traditionally reserved for public schools — a major source of early American education funding.
Common Mistakes
Forgetting that sections are numbered in a specific serpentine pattern within a township (1 in NE, snaking to 36).
Educational Tips
The US west of Ohio is largely divided into a grid of 1-mile sections. Look at Google Maps in rural areas to see the grid patterns.
About Square Foot (ft²)
Definition
The square foot is an imperial unit of area equal to the area of a square with sides of exactly one foot (0.0929 m²).
Mathematical Relationship
1 ft² = 144 in² = 0.0929 m² ≈ 929 cm². 9 ft² = 1 yd². 43,560 ft² = 1 acre.
Conversion Formula
To convert ft² to m²: multiply by 0.0929. To acres: divide by 43,560.
Practical Applications
Home and apartment sizes, office space, flooring calculations, carpet area, and construction specifications.
Interesting Facts
The average new US home is about 2,300 ft² (214 m²). The White House has about 55,000 ft² of floor space.
Common Mistakes
Incorrectly converting: 1 m ≈ 3.28 ft, but 1 m² ≈ 10.76 ft² (not 3.28). You must square the factor.
Educational Tips
A 12" × 12" floor tile = exactly 1 ft². Counting tiles gives you the room's area in square feet directly.
