In a common square grid layout known as a 1,000-Acre Sectional System, adjacent parallel roads were 100 chains or 1 + 1 ⁄ 4 miles (2.0 km) apart, and arranged as ten 100-acre lots each 20 chains by 50 chains [7] so that two consecutive concession roads and two consecutive side roads enclosed a square of 1,000 acres (4.0 km 2).
The primary grid pattern is of quarter sections (1 ⁄ 2 mi × 1 ⁄ 2 mi (800 m × 800 m)). In U.S. land surveying under the Public Land Survey System (PLSS), a section is an area nominally one square mile (2.6 square kilometers), containing 640 acres (260 hectares), with 36 sections making up one survey township on a rectangular grid.

LSDs can be "quarter-quarter sections" (square land parcels roughly 1 ⁄ 4 mi [400 m] on a side, comprising roughly 40 acres [160,000 m 2] in area)—but this is not necessary. Many are other fractions of a section (a half-quarter section—roughly 80 acres [320,000 m 2] in area is common). LSDs may be square, rectangular, and occasionally ...
In the third phase of the survey (British Columbia, Alberta and most of Saskatchewan), townships are nominally 486 chains (6.08 mi; 9.78 km) east-west and 483 chains (6.04 mi; 9.72 km) north-south. [5] The actual area of a given township differs from the nominal because of systematic effects (due to the design of the survey) and surveying errors.
Map of the boundary stones. The District of Columbia (initially, the Territory of Columbia) was originally specified to be a square 100 square miles (260 km 2) in area, with the axes between the corners of the square running north-south and east-west, The square had its southern corner at the southern tip of Jones Point in Alexandria, Virginia, at the confluence of the Potomac River and ...
"A league and a labor" (4,605.5 acres; 18.638 km 2) was a common first land grant [4] and consisted of a league of land away from the river plus one extra labor of good riparian (river-situated) land. A headright of this much land was granted to "all persons [heads of families] except Africans and their descendants and Indians living in Texas ...
One acre equals 1 ⁄ 640 (0.0015625) square mile, 4,840 square yards, 43,560 square feet, [2] or about 4,047 square metres (0.4047 hectares) (see below).While all modern variants of the acre contain 4,840 square yards, there are alternative definitions of a yard, so the exact size of an acre depends upon the particular yard on which it is based.
