How to Convert Section to Square Dekameter
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) = 25899.8811 Square Dekameter (dam²).

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 Dekameter (dam²)
Definition
The square dekameter is a metric unit of area equal to 100 square meters, also known as an 'are'.
Mathematical Relationship
1 dam² = 100 m² = 1 are = 0.01 ha = 0.001 hm².
Conversion Formula
To convert dam² to m²: multiply by 100. To hectares: divide by 100.
Practical Applications
Occasionally used for small land parcels in European property descriptions.
Interesting Facts
The 'are' is one of the few metric units that's almost completely obsolete — even the hectare (which means '100 ares') overshadowed it.
Common Mistakes
Confusing dam² (square dekameter, 100 m²) with dm² (square decimeter, 0.01 m²) — they differ by a factor of 10,000.
Educational Tips
Think: 1 are = 10 m × 10 m = 100 m². A hectare = 100 ares. The 'hect-' prefix means 100.
