The rod is useful as a unit of length because integer multiples of it can form one acre of square measure (area). The 'perfect acre' [2] is a rectangular area of 43,560 square feet, bounded by sides 660 feet (a furlong) long and 66 feet (a chain) wide (220 yards by 22 yards) or, equivalently, 40 rods by 4 rods. An acre is therefore 160 square ...
The surveying perch measured 22 French feet. In French North America, it was also equal to 25 square perches, but the royal perch of 18 feet was used, yielding a vergée of 8100 square feet (854.7 m 2) In Guernsey, a vergée (Guernésiais: vergie) is 17,640 square feet (1,639 m 2). It is 40 (square) Guernsey perches.
Rood is an English unit of area equal to one quarter of an acre [2] or 10,890 square feet, exactly 1,011.7141056 m 2. A rectangle that is one furlong (i.e., 10 chains, or 40 rods) in length and one rod in width is one rood in area, as is any space comprising 40 perches (a perch being one square rod).

1 acre (both variants) is equal to the following customary units: 66 feet × 660 feet (43,560 square feet) 10 square chains (1 chain = 66 feet = 22 yards = 4 rods = 100 links) 1 acre is approximately 208.71 feet × 208.71 feet (a square) 4,840 square yards; 43,560 square feet; 160 perches. A perch is equal to a square rod (1 square rod is 0. ...
This was the main square perch in old French surveying. It is a square 22 pieds du roi on each side. vergée: 12 100 ~1277 m 2 ~1527 sq yd A square 5 perches on each side, or one quarter of an acre. acre, or arpent carré: 48 400 ~5107 m 2 ~6108 sq yd, or ~1.262 acres The French acre is a square 10 perches (one arpent) on each side.

{{convert|100|lb|kg}} → 100 pounds (45 kg) The unit-codes should be treated as case-sensitive: {{convert|100|Mm|mm}} → 100 megametres (1.0 × 10 11 mm) The output of {{convert}} can display multiple converted units, if further unit-codes are specified after the second unnamed parameter (without the pipe separator). Typical combination ...
The agricultural foot was reduced to 10 ⁄ 11 of its former size, causing the rod, pole or perch to become 16 + 1 ⁄ 2 (rather than the older 15) agricultural feet. The furlong and the acre, once it became a measure of the size of a piece of land rather than its value, remained relatively unchanged. In the last thousand years, three principal ...
