About these units

Square Inch (in²)

US & ImperialCurrent unit

A square one inch on a side, exactly 6.4516 cm². Used for small parts and for pressure (pounds per square inch).

Latin uncia, one twelfth, gave English the inch, which Old English borrowed as ynce. A statute of Edward II in 1324 defined it as three barleycorns, dry and round, set end to end, and the barleycorn remained the base for centuries after 1066. The modern square inch rests on a 20th-century agreement: the United States adopted a yard of exactly 0.9144 meter on 1 July 1959, the United Kingdom followed effective 1 January 1964, and the inch became exactly 25.4 mm.

Squaring that gives exactly 6.4516 cm² for one square inch, and one square meter is about 1,550 of them. Its best-known descendant is the pound per square inch, psi, the pressure unit still used for American tires and air tanks: atmospheric pressure at sea level is about 14.7 psi, a car tire is typically inflated to around 32 psi above the surrounding air, and one psi is about 6.895 kilopascals. The square inch itself is common in the US and UK for small parts and printed material.

1 square inch = 0.00064516 square meters (exactly).

Guntha (guntha)

Indian subcontinentTraditional unit (still used in some regions)

1,089 square feet (about 101.17 m²). A land unit used in Maharashtra, Gujarat and Karnataka; 40 guntha make an acre.

A guntha is a small land measure used on the Indian subcontinent, and in India it is defined as a square 33 feet on a side. That gives 1,089 square feet, or about 101.17 square metres (120.999 square yards), and 40 gunthas make one acre. The guntha therefore acts as the fraction below the acre in plot sizes.

The size changes across the border. In Pakistan the unit is counted as 120 square yards, with 4 guntha to a jareeb and 10 jareeb to an acre, so the 40-to-an-acre ratio survives even though the guntha itself is a little smaller. Sub-units differ as well. In India a guntha holds 16 annas of about 6.32 square metres each, while in Pakistan 6 annas of 20.16 square yards make a guntha.

Wikipedia cites a 1966 United Nations handbook for the Pakistani values and says the units were used alongside the Imperial measures. The figure used here is the Indian one, 1,089 square feet. In metric terms a guntha is a little over 100 square metres.

1 guntha = 101.1714106 square meters (approximately).
