About these units

Square Wa (Thai) (sq wa)

ThaiTraditional unit (still used in some regions)

A square 2 meters on a side: exactly 4 m². Thai property prices are often quoted per square wa.

Tarang wa, the Thai name behind the English square wa, literally refers to a grid of wa. It is the smallest standard Thai land unit, the area of a square with sides of one wa, so with a wa of 2 meters it equals 4 square meters.

One hundred square wa form a ngan and 400 form a rai. Because it is so small, it is the unit in which urban plots and condominium-adjacent land are usually priced, and listings often quote a price per square wa.

Its value is the square of the wa, so any change to the wa would flow straight through, but the metric definition has been fixed since the cadastral survey of the Royal Thai Survey Department began in 1896. A typical townhouse lot of 20 square wa is therefore 80 square meters.

1 square wa (Thai) = 4 square meters (exactly).

Square Yard (yd²)

US & ImperialCurrent unit

9 square feet (0.8361 m²). Used for carpet, turf and land in the UK and India (where it is called a gaj).

Branches and rods lie behind this unit. The word yard comes from Old English gerd or gyrd, meaning a staff or measuring rod, and it first appears in the late seventh-century laws of Ine of Wessex, where a yard of land was a tax unit. Where its length came from is uncertain: pacing, the cubit and the arm of King Henry I have all been suggested. A square yard is simply a square of that length on each side.

After the 1959 agreement among six countries fixed the yard at exactly 0.9144 meter, the square yard became exactly 9 square feet, 1,296 square inches or about 0.836 m². It is used across the English-speaking world, notably in the United States, United Kingdom, Canada, India and Pakistan. In northern India it is called a gaj, and in Pakistan a gaz, and house plots there are often quoted in it. In the US and UK the yard, divided into eighths, is also how cloth is bought, so the square yard suits flooring and fabric in the same breath.

1 square yard = 0.83612736 square meters (exactly).
