pound. The pound or pound-mass is a unit of mass used in both the British imperial and United States customary systems of measurement. Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly 0.45359237??kilograms, and which is divided into 16 avoirdupois ounces. The international standard symbol for the avoirdupois pound is lb; an alternative symbol is lbm, #, and ??? or ?????.

carat. The carat (ct) is a unit of mass equal to 200??mg, which is used for measuring gemstones and pearls. The current definition, sometimes known as the metric carat, was adopted in 1907 at the Fourth General Conference on Weights and Measures, and soon afterwards in many countries around the world. The carat is divisible into 100 points of 2??mg. Other subdivisions, and slightly different mass values, have been used in the past in different locations.

light-year. A light-year, alternatively spelled light year, is a unit of length used to express astronomical distances and is equal to exactly 9460730472580.8??km, which is approximately 9.46 trillion kilometres or 5.88 trillion miles. As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year. Despite its inclusion of the word "year", the term is not a unit of time.

astronomical unit. The astronomical unit is a unit of length defined as 149597870700??m. Historically, the astronomical unit was conceived as the average Earth-Sun distance, before its modern redefinition in 2012.

Planck length. In particle physics and physical cosmology, Planck units are a system of units of measurement defined exclusively in terms of four universal physical constants: c, G, ??, and kB. Expressing one of these physical constants in terms of Planck units yields a numerical value of 1. They are a system of natural units, defined using fundamental properties of nature rather than properties of a chosen prototype object. Originally proposed in 1899 by German physicist Max Planck, they are relevant in research on unified theories such as quantum gravity.

acre. The acre is a unit of land area used in the British imperial and the United States customary systems. It is traditionally defined as the area of one chain by one furlong, which is exactly equal to 10 square chains, 1???640 of a square mile, 4,840 square yards, or 43,560 square feet, and approximately 4,047??m2, or about 40% of a hectare. The acre is sometimes abbreviated ac, but is usually spelled out as the word "acre".

homestead. A survey township, sometimes called a Congressional township or just township, as used by the United States Public Land Survey System and by Canada's Dominion Land Survey is a nominally-square area of land that is nominally six survey miles on a side. Each 36-square-mile township is divided into 36 sections of one square mile each. The sections can be further subdivided for sale.

Volume

minim. The minim is a unit of volume in both the imperial and U.S. customary systems of measurement. Specifically, in the imperial system, it is 1???60 of an imperial fluid drachm or 1???480 of an imperial fluid ounce; in the U.S. customary system, it is 1???60 of a US customary fluid dram or 1???480 of a US customary fluid ounce.

Length

foot. The foot is a unit of length in the British imperial and United States customary systems of measurement. The prime symbol, ???, is commonly used to represent the foot. In both customary and imperial units, one foot comprises 12??inches, and one yard comprises three feet. Since an international agreement in 1959, the foot is defined as equal to exactly 0.3048??meters. The most common plural of foot is feet. However, the singular form may be used like a plural when it is preceded by a number, as in "that man is six foot tall". Footage is the term used informally for a length expressed in feet.

inch. The inch is a unit of length in the British Imperial and the United States customary systems of measurement. It is equal to ???1/36??? yard or ???1/12??? of a foot. Derived from the Roman uncia ("twelfth"), the word inch is also sometimes used to translate similar units in other measurement systems, usually understood as deriving from the width of the human thumb.

yard. The yard is an English unit of length in both the British imperial and US customary systems of measurement equalling 3??feet or 36??inches. Since 1959 it has been by international agreement standardized as exactly 0.9144??meter. A distance of 1,760??yards is equal to 1 mile.

square foot. The square foot is an imperial unit and U.S. customary unit of area, used mainly in the United States, Canada, the United Kingdom, Bangladesh, India, Nepal, Pakistan, Ghana, Liberia, Malaysia, Myanmar, Singapore and Hong Kong. It is defined as the area of a square with sides of 1 foot.

nautical mile. A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. Historically, it was defined as the meridian arc length corresponding to one minute of latitude at the equator, so that Earth's polar circumference is very near to 21,600 nautical miles. Today the international nautical mile is defined as exactly 1,852 metres. The derived unit of speed is the knot, one nautical mile per hour.

mile. The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of length; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. The statute mile was standardised as a unit of length between the Commonwealth of Nations and the United States by an international agreement in 1959, when the yard was formally redefined with respect to SI units as 0.9144??metres, making the mile exactly 1609.344 metres. For everyday use, five miles equates roughly to eight kilometres. Mileage is the term used informally for a distance expressed in miles.

furlong. A furlong is a measure of distance in imperial units and United States customary units equal to one-eighth of a mile, equivalent to any of 660??feet, 220??yards, 40??rods or perches, 10??chains, or approximately 201??metres. It is now mostly confined to use in horse racing, where in many countries it is the standard measurement of race lengths, and agriculture, where it is used to measure rural field lengths and distances specifically in the United Kingdom, Ireland, Canada, and the United States.
