About these units
Are (a)
An are is a metric land unit equal to 100 m², originally invented during the development of the metric system but now largely overshadowed by the hectare (100 ares). Although rarely used independently in modern measurement, the are survives in real estate transactions in parts of Europe, where small land parcels—such as garden plots or rural homesteads—may be expressed in ares. It remains important historically, as it served as a transitional unit bridging the earliest metric innovations with modern large-scale land measurement practices.
Square Rod (US Survey) (rod² (US))
The US survey square rod is defined using the survey foot and differs negligibly from the international square rod. This distinction matters in legal contexts, especially when interpreting older property descriptions dating back to the 19th-century PLSS-era surveys. The unit persists primarily in legal documents and rural land records, ensuring that historical boundaries remain consistent even as measurement standards evolve.
