Do calculations with units

範例共 4 個步驟，在同一個工作階段中依序執行。每一步都在引擎上實際執行過，下方的輸出就是它產生的結果。

步驟 1

Quantity[19.25, "Kilometers"] + Quantity[13, "Miles"]

輸出

Quantity[40.171472, Kilometers]

步驟 2

Quantity[20, "Feet"] / Quantity[2.3, "Seconds"] + Quantity[9, "Meters" / "Seconds"]

輸出

Quantity[38.22321122903116, Feet/Seconds]

步驟 3

N[Quantity[175, "Pounds"] / Quantity[100, "Kilograms"]]

輸出

0.7937866475

步驟 4

Quantity[24, "Miles" / "Gallons"] * Quantity[16.2, "Gallons" / IndependentUnit["tank"]] * Quantity[1 / 8, IndependentUnit["tank"]]

輸出

Quantity[48.599999999999994, Miles/Gallons*Gallons/IndependentUnit["tank"]*IndependentUnit["tank"]]
