An acre-foot is a unit of volume commonly used in the United States in reference to large-scale water resources, such as reservoirs, aqueducts, canals, sewer flow capacity, and river flows. It is defined by the volume of one acre of surface area to a depth of one foot. Since the acre is defined as a chain by a furlong (\\(66 ft \\times 660 ft\\)) the acre-foot is exactly \\(43,560 cubic feet\\). For irrigation water, the volume of \\(1 ft \\times 1 \\; ac = 43,560 \\; ft^{3} (1,233.482 \\; m^{3}, 325,851 \\; US gal)\\).

The \\(Angstr\\ddot{o}m\\) is an internationally recognized unit of length equal to \\(0.1 \\,nanometre\\) or \\(1 \\times 10^{-10}\\,metres\\). Although accepted for use, it is not formally defined within the International System of Units(SI). The angstrom is often used in the natural sciences to express the sizes of atoms, lengths of chemical bonds and the wavelengths of electromagnetic radiation, and in technology for the dimensions of parts of integrated circuits. It is also commonly used in structural biology.

The area in circular mils, A, of a circle with a diameter of d mils, is given by the formula: Electricians in Canada and the United States are familiar with the circular mil because the National Electrical Code (NEC) uses the circular mil to define wire sizes larger than 0000 AWG. In many NEC publications and uses, large wires may be expressed in thousands of circular mils, which is abbreviated in two different ways: MCM or kcmil. For example, one common wire size used in the NEC has a cross-section of 250,000 circular mils, written as 250 kcmil or 250 MCM, which is the first size larger than 0000 AWG used within the NEC.

Note that these definitions are different from a typewriter's pica setting, which denotes a type size of ten characters per horizontal inch."^^rdf:HTML ; qudt:hasQuantityKind quantitykind:Length ; qudt:id "U150E1360" ; qudt:symbol "PCA" ; qudt:ucumCode "[PCA]"^^qudt:UCUMci-term ; qudt:ucumCode "[pca]"^^qudt:UCUMcs-term ; rdfs:isDefinedBy ; rdfs:isDefinedBy unit:space-and-time ; rdfs:label "Pica" ; skos:exactMatch ; skos:prefLabel "pica" ; prov:wasInfluencedBy ; . unit:PER-HR rdf:type qudt:DerivedUnit ; rdf:type qudt:FrequencyUnit ; rdf:type qudt:Unit ; qudt:abbreviation "m^{-1}" ; qudt:code "0875" ; qudt:conversionMultiplier 3.6e2 ; qudt:conversionOffset "0.0"^^xsd:double ; qudt:description "A reciprocal unit of time for $\\textit{reciprocal hour}$ or \"inverse hour\"."^^rdf:HTML ; qudt:hasQuantityKind quantitykind:Frequency ; qudt:symbol "h^{-1}" ; qudt:ucumCode "HR-1"^^qudt:UCUMci ; qudt:ucumCode "h-1"^^qudt:UCUMcs ; rdfs:isDefinedBy ; rdfs:isDefinedBy unit:space-and-time ; rdfs:label "Per Hour" ; skos:prefLabel "inverse-hour" ; . unit:PER-M rdf:type qudt:AcousticsUnit ; rdf:type qudt:SpaceAndTimeUnit ; rdf:type qudt:Unit ; qudt:abbreviation "per-meter" ; qudt:code "1091" ; qudt:conversionMultiplier "1"^^xsd:double ; qudt:conversionOffset "0.0"^^xsd:double ; qudt:description "Per Meter Unit is a a demominator unit with dimensions $/m$."^^rdf:HTML ; qudt:hasQuantityKind quantitykind:InverseLength ; qudt:id "U150E1091" ; qudt:symbol "m^{-1}" ; qudt:ucumCode "M-1"^^qudt:UCUMci ; qudt:ucumCode "m-1"^^qudt:UCUMcs ; rdfs:isDefinedBy ; rdfs:isDefinedBy unit:space-and-time ; rdfs:label "Per Meter" ; skos:prefLabel "per-meter" ; . unit:PER-M3 rdf:type qudt:SpaceAndTimeUnit ; rdf:type qudt:Unit ; qudt:abbreviation "/m^3" ; qudt:code "1091" ; qudt:conversionMultiplier "1"^^xsd:double ; qudt:conversionOffset "0.0"^^xsd:double ; qudt:description "\"Per Cubic Meter\" is a demominator unit with dimensions $/m^3$."^^rdf:HTML ; qudt:hasQuantityKind quantitykind:InverseVolume ; qudt:id "U150E1096" ; qudt:symbol "m^{-3}" ; qudt:ucumCode "M-3"^^qudt:UCUMci ; qudt:ucumCode "m-3"^^qudt:UCUMcs ; rdfs:isDefinedBy ; rdfs:isDefinedBy unit:space-and-time ; rdfs:label "Per Cubic Meter" ; skos:prefLabel "per-cubic-meter" ; . unit:PER-MIN rdf:type qudt:DerivedUnit ; rdf:type qudt:FrequencyUnit ; rdf:type qudt:Unit ; qudt:abbreviation "m^{-1}" ; qudt:code "0875" ; qudt:conversionMultiplier "60.0"^^xsd:double ; qudt:conversionOffset "0.0"^^xsd:double ; qudt:description "A reciprocal unit of time for $\\textit{reciprocal minute}$ or $\\textit{inverse minute}$."^^rdf:HTML ; qudt:hasQuantityKind quantitykind:Frequency ; qudt:symbol "m^{-1}" ; qudt:ucumCode "MIN-1"^^qudt:UCUMci ; qudt:ucumCode "min-1"^^qudt:UCUMcs ; rdfs:isDefinedBy ; rdfs:isDefinedBy unit:space-and-time ; rdfs:label "Per Minute" ; skos:prefLabel "inverse-minute" ; . unit:PER-SEC rdf:type qudt:DerivedUnit ; rdf:type qudt:FrequencyUnit ; rdf:type qudt:Unit ; qudt:abbreviation "sec^{-1}}" ; qudt:code "0875" ; qudt:conversionMultiplier "1.0"^^xsd:double ; qudt:conversionOffset "0.0"^^xsd:double ; qudt:description "A reciprical unit of time for $\\textit{reciprocal second}$ or $\\textit{inverse second}$.

The radian is represented by the symbol \"rad\" or, more rarely, by the superscript c (for \"circular measure\"). For example, an angle of 1.2 radians would be written as \"1.2 rad\" or \"1.2c\" (the second symbol is often mistaken for a degree: \"1.2u00b0\"). As the ratio of two lengths, the radian is a \"pure number\" that needs no unit symbol, and in mathematical writing the symbol \"rad\" is almost always omitted.

In physics, the Planck time, denoted by \\(tP\\), is the unit of time in the system of natural units known as Planck units. It is the time required for light to travel, in a vacuum, a distance of 1 Planck length. The unit is named after Max Planck, who was the first to propose it.

\\(t_p \\equiv \\sqrt{\\frac{\\hbar G}{c^5}} \\approx 5.39106(32) \\times 10^{-44} s\\)

where,

\\(c\\) is the speed of light in a vacuum,
\\(\\hbar\\) is the reduced Planck's constant (defined as \\(\\hbar = \\frac{h}{2 \\pi}\\)), and
\\(G\\) is the gravitational constant.

The two digits between parentheses denote the standard error of the estimated value.

Since antiquity, astronomers have progressively refined the definition of the tropical year, and currently define it as the time required for the mean Sun's tropical longitude (longitudinal position along the ecliptic relative to its position at the vernal equinox) to increase by 360 degrees (that is, to complete one full seasonal circuit)."^^rdf:HTML ; qudt:hasQuantityKind quantitykind:Time ; qudt:id "U150E1990" ; qudt:symbol "a_{t}" ; qudt:ucumCode "ANN_T"^^qudt:UCUMci-term ; qudt:ucumCode "a_t"^^qudt:UCUMcs-term ; rdfs:isDefinedBy ; rdfs:isDefinedBy unit:space-and-time ; rdfs:label "Tropical Year" ; skos:prefLabel "tropical-year" ; . unit:Year365Day rdf:type qudt:Unit ; qudt:abbreviation "year365day" ; qudt:conversionOffset "0.0"^^xsd:double ; qudt:hasQuantityKind quantitykind:Time ; rdfs:isDefinedBy ; rdfs:isDefinedBy unit:space-and-time ; . unit:YearTropical rdf:type qudt:Unit ; qudt:abbreviation "yeartropical" ; qudt:conversionOffset "0.0"^^xsd:double ; qudt:hasQuantityKind quantitykind:Time ; qudt:ucumCode "ANN_T"^^qudt:UCUMci-term ; qudt:ucumCode "a_t"^^qudt:UCUMcs-term ; rdfs:isDefinedBy ; rdfs:isDefinedBy unit:space-and-time ; owl:sameAs unit:YR_TROPICAL ; . unit:tP rdf:type qudt:TimeUnit ; qudt:abbreviation "tP" ; qudt:conversionMultiplier 5.39124E-44 ; qudt:conversionOffset "0.0"^^xsd:double ; qudt:description """

In physics, the Planck time, denoted by \\(tP\\), is the unit of time in the system of natural units known as Planck units. It is the time required for light to travel, in a vacuum, a distance of 1 Planck length. The unit is named after Max Planck, who was the first to propose it.

\\(t_p \\equiv \\sqrt{\\frac{\\hbar G}{c^5}} \\approx 5.39106(32) \\times 10^{-44} s\\)

where,

\\(c\\) is the speed of light in a vacuum,
\\(\\hbar\\) is the reduced Planck's constant (defined as \\(\\hbar = \\frac{h}{2 \\pi}\\)), and
\\(G\\) is the gravitational constant.

The two digits between parentheses denote the standard error of the estimated value.

The Space and Time Units Vocabulary covers the defining units for the Imperial, SI and US Customary units of measure for space and time.

Where possible naming conventions for units respect the well-known abbreviations for units. These conventions are documented in the QUDT Name and Identifier Rules specification. When a name is overloaded, a discriminator is added. For example, \\(OZ\\) and \\(US\\,Liquid\\,OZ\\) have the same abbreviation \\(OZ\\). The discriminator in this case is the suffix \\(US\\) for the latter unit of measure. Many units can be scaled with decimal prefixes such as \\(kilo\\) and \\(micro\\).
