Comparison of 1 square yard with some Imperial and metric units of area The square yard ( Northern India : gaj , Pakistan : gaz ) is an imperial unit and U.S. customary unit of area . It is in widespread use in most of the English -speaking world, particularly the United States, United Kingdom, Canada, Pakistan and India.
The MERU, or Milli Earth Rate Unit, is an angular velocity equal to 1/1000 of Earth's rotation rate. It was introduced by MIT's Instrumentation Laboratories (now Draper Labs) to measure the performance of inertial navigation systems. [79] One MERU = 7.292 115 × 10 ^ −8 radians per second [80] or about 0.2625 milliradians/hour.
the relationship between square feet and square inches is 1 square foot = 144 square inches, where 144 = 12 2 = 12 × 12. Similarly: 1 square yard = 9 square feet; 1 square mile = 3,097,600 square yards = 27,878,400 square feet; In addition, conversion factors include: 1 square inch = 6.4516 square centimetres; 1 square foot = 0.092 903 04 ...
A yard line refers to the distance of some point on the 100-yard field of play – usually the line of scrimmage or the spot where a play ends – from the nearest goal line. [6] When moving away from one goal line, the yard line numbers increase from 1 to 50 (midfield), then decrease back to 1 approaching the opposite goal line.
Respectively, these square divisions of land are approximately 80 chains (one mile or 1.6 km), 40 chains (half a mile or 800 m), and 20 chains (a quarter mile or 400 m) on a side. The chain is still used in agriculture: measuring wheels with a circumference of 0.1 chain (diameter ≈ 2.1 ft or 64 cm) are still readily available in Canada and ...
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.
New conversion factors for the rod and furlong as 16.5 international feet and 660 international feet respectively have been published by NIST. [71] However, it is not clear if a "survey yard" actually exists. [72] If it did, its hypothetical values would be as follows: 3937 survey yards = 3600 meters [69] 1 survey yard ≈ 0.914 401 83 meters [69]
An area of land one chain (four rods) wide by one furlong in length. As the traditional furlong could vary in length from country to country, so did the acre. In England an acre was 4,840 square yards (4,050 m 2), in Scotland 6,150 square yards (5,140 m 2) and in Ireland 7,840 square yards (6,560 m 2). It is a Saxon unit, meaning "field".
