What is are?

An are is a metric unit of area equal to 100 square metres. While largely replaced by the hectare for most practical uses, it is still referenced in some European countries for measuring agricultural plots.

Real-world uses

The are (100 m²) is used in some European countries for small land parcels and garden plots. In France, small agricultural plots and building lots may be listed in ares. It is most commonly encountered as the basis for the hectare (100 ares).

History

The are was defined in 1795 during the creation of the metric system in France as 100 square metres. Though the hectare eclipsed it in common usage, the are remains a legally recognized metric unit in several European countries.

Common mistakes

Confusing the are (a unit of area equal to 100 m²) with the word "are" (verb). Also, many people are unfamiliar with this unit and do not realize that 1 hectare = 100 ares.

What is square yard?

A square yard is a unit of area in imperial and US customary systems equal to 9 square feet. It is used in carpet and fabric measurement, as well as in construction and landscaping in the United States.

Real-world uses

Square yards are used for carpet and flooring sales in the US and UK, fabric quantities, and some land area descriptions. Cricket pitch dimensions are often discussed in square yards. Landscaping materials like sod are sometimes sold per square yard.

History

The square yard is a natural extension of the yard measurement. It has been used in the British and American textile trade for centuries, where fabric is traditionally measured in linear yards but flooring and carpeting in square yards.

Common mistakes

Confusing square yards with square feet—1 square yard equals 9 square feet (3 ft × 3 ft), not 3 square feet. This error often leads to significant under- or over-ordering of materials.

When is this conversion used?

Converting between are and square yard is common when working across metric and imperial systems, such as international trade, travel between countries with different measurement standards, or following instructions from a different region.
