About these units

Township (twp)

US land surveyTraditional unit (still used in some regions)

36 sections: a square 6 survey miles on a side (23,040 acres). Used in US land records.

Western descriptions of land such as T2N, R3E refer to townships in the survey sense: a block six miles on a side, nominally 36 square miles or 23,040 acres. T counts six-mile steps north or south of a baseline, while R counts six-mile steps east or west of a principal meridian. Each region's grid hangs from an initial point where the two meet, and one meridian can serve several states, as the Willamette Meridian does for Oregon and Washington.

Meridians converge toward the pole, so townships would shrink to the north if nothing were done. Surveyors therefore laid standard parallels, commonly every 24 or 30 miles, to reset the width. The first lands laid out this way were the Seven Ranges in eastern Ohio, and Jefferson is credited with promoting the system to support a country of independent farmers. A survey township is distinct from a civil township, which is a unit of local government in about 20 states and may follow the survey lines or ignore them.

1 township = 93,239,944.93 square meters (approximately).

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).
