Conversion accuracy depends on the exact US survey foot definition
-
Digital handling of large numbers requires careful attention
Frequently Asked Questions
-
What is a square rod (US survey)?
-
It is an area unit defined by the area of a square whose sides each measure one US survey rod, equivalent to 272.25 square US survey feet.
-
What does a square decimeter represent?
-
A square decimeter [dm²] is the area of a square with sides of one decimeter, equal to 0.01 square meters or 100 square centimeters.
-
Why convert square rods to square decimeters?
-
Conversion translates legacy land measurements into modern metric units for accurate, scientific, or small-scale applications.
Key Terminology
-
Square Rod (US Survey)
-
A traditional area unit defined as a square with 16.5 US survey feet sides, equal to 272.25 square US survey feet.
-
Square Decimeter [dm²]
-
An SI unit representing the area of a square with 1 decimeter sides; 1 dm² equals 0.01 m².
