Land and Surveying Unit Converter

Convert property, agriculture, landscaping, and construction measurements among metric land areas, acres, hectares, nominal sections, square distance units, chains, rods, links, and feet. Area and length stay separate. Modern U.S. customary and imperial foot-based units use the exact international foot; legacy U.S. survey-foot options are clearly marked. Calculate it clearly with Figur.

How the land and surveying unit converter works

Convert property, agriculture, landscaping, and construction measurements among metric land areas, acres, hectares, nominal sections, square distance units, chains, rods, links, and feet. Area and length stay separate. Modern U.S. customary and imperial foot-based units use the exact international foot; legacy U.S. survey-foot options are clearly marked.

Method and assumptions

Figur converts each area unit to square meters or each length unit to meters, then into the target unit. It never converts area to length. Modern foot-based units use the exact international foot, 1 ft = 0.3048 m; legacy options use 1 U.S. survey ft = 1200/3937 m.

  • Source and target units represent the same physical dimension: area with area or length with length.
  • Modern chains, rods, and links use 66, 16.5, and 0.66 international feet respectively; U.S. survey-foot variants are marked legacy.
  • A PLSS section is treated as a nominal 640 acres; actual surveys, correction lots, and title records can produce a different area.

Unit conversion only. It does not transform coordinates, bearings, or GIS systems and does not determine boundaries, title, legal acreage, or survey compliance. Historical and regional definitions can vary; confirm the datum, deed, and governing standards with a licensed surveyor.

Worked example

Convert 1 nominal PLSS section to modern acres.

1 nominal section equals 640 ac.

Frequently asked questions

Can I convert an area into a survey length?

No. Square units and length units describe different dimensions, so Figur rejects cross-dimension pairs instead of inventing a result.

Why are some units marked legacy or nominal?

The U.S. survey foot was retired after 2022 except for historical records. A PLSS section is nominally 640 acres, but surveyed boundaries, correction lots, and local records can differ.
