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.

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.

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.

fathom. A fathom is a unit of length in the imperial and U.S. customary systems equal to 6 feet (1.8288??m), used especially for measuring the depth of water. The fathom is neither an international standard (SI) unit, nor an internationally accepted non-SI unit. Historically, it was the maritime measure of depth in the English-speaking world but, apart from within the US, charts now use metres.

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.

cubic foot. The cubic foot is an imperial and US customary (non-metric) unit of volume, used in the United States and the United Kingdom. It is defined as the volume of a cube with sides of one foot in length, or exactly 28.316846592??L.

femtometre. The femtometre, symbol fm, is a unit of length in the International System of Units (SI) equal to 10???15 metres, which means a quadrillionth of one metre. This distance is sometimes called a fermi and was so named in honour of Italian naturalized to American physicist Enrico Fermi, as it is a typical length-scale of nuclear physics.

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.

attoparsec. Many people have made use of, or invented, units of measurement intended primarily for their humor value. This is a list of such units invented by sources that are notable for reasons other than having made the unit itself, and that are widely known in the Anglophone world for their humor value.

Mass
femtogram. To help compare different orders of magnitude, the following lists describe various mass levels between 10???67 kilograms (kg) and 1052 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe. Typically, an object having greater mass will also have greater weight (see mass versus weight), especially if the objects are subject to the same gravitational field strength.

microgram. In the metric system, a microgram or microgramme is a unit of mass equal to one millionth of a gram. Two different abbreviations are commonly used. The International System of Units (SI) uses ??g, where the SI prefix "micro-" is represented by the Greek letter ?? (mu). The abbreviation mcg is preferred for medical information in the United States (US), but prescription writing guidance in the United Kingdom advises that "microgram" should not be abbreviated. A third abbreviation, the Greek letter ?? (gamma), is no longer recommended. The US Institute for Safe Medication Practices (ISMP) and the US Food and Drug Administration (FDA) recommend that mcg should be used, rather than ??g, when communicating medical information. This is due to the risk that ?? might be misread as m, for "milli-", which is equal to one thousandth. Such a misreading could result in a thousandfold overdose of a drug or medicine. However, mcg is also the symbol for the obsolete unit millicentigram, derived from the centimetre???gram???s
