About these units
Square Mile (mi²)
640 acres or about 2.59 km². Used for the area of cities, states and countries in the US and UK.
A thousand Roman paces, mille passus, became the mile, and under Elizabeth I Parliament fixed the statute mile at eight furlongs, or 5,280 feet, in place of the older Roman-based value. The square mile inherits that length. Its most famous use came in the United States: the Land Ordinance of 1785 started the Public Land Survey System so that western land could be surveyed and sold to pay war debts, beginning with the Seven Ranges in eastern Ohio.
In that system a section is roughly one square mile, or 640 acres, and a township is 36 sections in a square six miles on a side. One square mile is nearly 2.59 million square meters. Chicago's Midway International Airport, at about 650 acres, covers roughly 1.02 square miles. Beware the phrase mile square: a region 20 miles square has 400 square miles, but so does a rectangle 10 by 40 miles. The US survey version of the mile was retired from 1 January 2023, but the international square mile remains the unit for cities, states and countries in the US and UK.
1 square mile = 2,589,988.11 square meters (approximately).

Square Wa (Thai) (sq wa)
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).
