To convert sections to acres: multiply by 640. To km²: multiply by 2.59.
1 section = 1 mi² = 640 acres = 2.59 km². 36 sections = 1 township.
For example, 1 Section (section) = 25899881100 Square Centimeter (cm²).

Rural property descriptions, agricultural land division, mineral rights, and road grid planning in the western US.
Section 16 in every township was traditionally reserved for public schools — a major source of early American education funding.
Forgetting that sections are numbered in a specific serpentine pattern within a township (1 in NE, snaking to 36).
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.
The square centimeter is a metric unit of area equal to 0.0001 square meters, or the area of a square 1 cm on each side.
1 cm² = 0.0001 m² = 100 mm² ≈ 0.155 in². There are 10,000 cm² in 1 m².
To convert cm² to in²: multiply by 0.155. To m²: divide by 10,000. To mm²: multiply by 100.
Wound sizes in medicine, postage stamp dimensions, fabric samples, phone screen sizes, and cross-sectional areas.
A US postage stamp is about 5 cm². The surface area of human skin is about 18,000 cm² (1.8 m²). A fingernail is about 1 cm².
Squaring incorrectly: 3 cm × 4 cm = 12 cm², not 12 cm. Units must be squared for area.
Your fingernail is roughly 1 cm². A credit card is about 46 cm². These are easy visual references.
