CommonUnits[{quantity1,quantity2,…,quantityn}]

互換性のある次元において，quantity1 から quantityn までを共通単位に変換する．

詳細

  • CommonUnitsは，入力リストの単位を次元が等しい下位区分ごとに共通単位に変換する．
  • CommonUnitsは発見的なメソッドを使って入力データに最も適した単位を選ぶ．
  • 通貨単位を含む操作にはインターネット接続が必要である．

例  (2)

長さのリストを共通単位に変換する：

Wolfram Language code: CommonUnits[{Quantity[2, "Feet"], Quantity[30, "Inches"], Quantity[0.25, "Meters"]}]

長さと質量のすべての単位を共通単位に変換する：

Wolfram Language code: CommonUnits[{Quantity[10, "Feet"], Quantity[300, "Inches"], Quantity[45, "Pounds"], Quantity[12.2, "Kilograms"]}]

スコープ  (4)

CommonUnitsをQuantityオブジェクトのリストに使う：

Wolfram Language code: CommonUnits[{Quantity[3.2, "Meters"], Quantity[10, "Inches"], Quantity[7, "Feet"]}]
Wolfram Language code: CommonUnits[{Quantity[3.5, "Kilograms"], Quantity[3.5, "ChineseJins"], Quantity[3.5, "Pounds"]}]

CommonUnitsをQuantityArrayオブジェクトに使う：

Wolfram Language code: qa = QuantityArray[Transpose@{Range[100], Range[100]}, {"Meters", "Inches"}]
Wolfram Language code: CommonUnits[qa]

CommonUnitsは，IndependentUnit指定のある数量を変換することができる：

Wolfram Language code: qa = Quantity[5, "Kilo"IndependentUnit["Apples"] / "Meters" ^ 2]
Wolfram Language code: qb = Quantity[300, IndependentUnit["Apples"] / "Feet" ^ 2]
Wolfram Language code: CommonUnits[{N[qa], qb}]

CommonUnitsは，混合量を変換することができる：

Wolfram Language code: qa = Quantity[MixedMagnitude[{1, 80}], MixedUnit[{"Meters", "Centimeters"}]]
Wolfram Language code: qb = Quantity[MixedMagnitude[{5, 10}], MixedUnit[{"Feet", "Inches"}]]
Wolfram Language code: CommonUnits[{qa, N[qb]}]

特性と関係  (3)

CommonUnitsは，共通のUnitDimensionsを持つ数量を変換する：

Wolfram Language code: CommonUnits[{Quantity[0.5, "Teslas"], Quantity[200, "Gausses"], Quantity[10, "Webers"/"Dekameters"^2]}]
Wolfram Language code: UnitDimensions /@ {Quantity[0.5, "Teslas"], Quantity[200, "Gausses"], Quantity[10, "Webers"/"Dekameters"^2]}

CommonUnitsは，共通のUnitDimensionsを持つ数量の部分集合に作用する：

Wolfram Language code: CommonUnits[{Quantity[3., "Meters"/"Seconds"], Quantity[0.23, "Kilograms"], Quantity[40., "Miles"/"Hours"], Quantity[6.5, "Pounds"]}]
Wolfram Language code: GroupBy[{Quantity[3., "Meters"/"Seconds"], Quantity[0.23, "Kilograms"], Quantity[40., "Miles"/"Hours"], Quantity[6.5, "Pounds"]}, UnitDimensions]

CommonUnitsは，無次元単位の数量を純粋な数に変換する：

Wolfram Language code: {Quantity[7, "Percent"], Quantity[3, "Dozens"], Quantity[34, "PartsPerMillion"]}
Wolfram Language code: %//CommonUnits
