About these units

Kanal (kanal)

Indian subcontinentTraditional unit (still used in some regions)

20 marla or 5,445 square feet (505.86 m²). Used for property in Pakistan and north India.

Pakistani property listings give large plots in kanals, and the same word appears in Punjab and Haryana across the border. Under British rule the kanal was standardized as 20 marlas, which is 605 square yards or 5,445 square feet, about 505.857 square metres. That makes it exactly an eighth of an acre, so 8 kanals fill an acre, and a hectare holds about 19.77 kanals.

The kanal is the middle step in a ladder of Punjabi land units. Below it sit the marla and the sarsahi, and above it the bigha and the acre. The bigha itself is not constant: Wikipedia lists it as 4 kanals in Punjab but 5 kanals in eastern Uttar Pradesh and Bihar, which shows how little land units agree between regions.

Elsewhere in India other local names fill the same role. In east India 1 kanal is given as 4 katha in the article's list, while in Punjab it is 5 biswa. The figure used here is the Raj-era 5,445 square feet. A kanal is about 0.05 hectare.

1 kanal = 505.8570528 square meters (exactly).

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).
