QuantityMagnitude
QuantityMagnitude[quantity]
gives the amount of the specified quantity.
QuantityMagnitude[quantity,unit]
gives the value corresponding to quantity when converted to unit.
Details
- QuantityMagnitude returns the magnitude of Quantity[magnitude,unit].
- QuantityMagnitude[quantity,unit] is equivalent to QuantityMagnitude[UnitConvert[quantity,unit]].
- QuantityMagnitude accepts TimeSeries, EventSeries, and TemporalData inputs.

Give the magnitude value of a Quantity:
QuantityMagnitude[Quantity[3.4, "Meters"]]QuantityMagnitude[{["3 meters"], Quantity[32/3, "Meters"]}]Get the value of 1 hour in various units:
QuantityMagnitude[Quantity[1, "Hours"], #]& /@ {"Minutes", "Seconds"}Find the value of various quantities in kilograms:
QuantityMagnitude[{["3.5 pounds"], ["1.25 tonns"], ["2.1k ounces"]}, "Kilograms"]Scope (5)
Get the values from Quantity expressions in a time series:
data = MoonPosition[DateRange[DateObject[{2013, 1, 1}, "Day", "Gregorian", -6.], DateObject[{2013, 12, 31}, "Day", "Gregorian", -6.], 10]]data[{2013, 1, 20}]QuantityMagnitude[data]%[{2013, 1, 20}]QuantityMagnitude returns the dimensionless distribution of a QuantityDistribution:
𝒟 = TriangularDistribution[{Quantity[55, "Miles"/"Hours"], Quantity[82, "Miles"/"Hours"]}, Quantity[72, "Miles"/"Hours"]]QuantityMagnitude[𝒟]QuantityMagnitude accepts SparseArray specifications:
QuantityMagnitude[SparseArray[{1 -> Quantity[8, "Bits"], 2 -> Quantity[1, "Octets"]}]]QuantityMagnitude accepts structured arrays like QuantityArray and SymmetrizedArray objects:
QuantityMagnitude[QuantityArray[{1, 2, 3}, "Hectares"]]QuantityMagnitude[SymmetrizedArray[{{1, 1} -> Quantity[2, "Liters"], {2, 1} -> Quantity[3, "Newtons"], {2, 2} -> Quantity[4, "Joules"]},
{2, 2}, Symmetric[{1, 2}]]]QuantityMagnitude accepts Association objects:
QuantityMagnitude[<|"Distance" -> Quantity[260, "Miles"], "Duration" -> Quantity[3, "Hours"]|>]Properties & Relations (6)
QuantityMagnitude operates on lists of quantities:
QuantityMagnitude[{Quantity[3.2, "Meters"], Quantity[36, "Pounds"]}]QuantityMagnitude[{{Quantity[52, "Weeks"], Quantity[20, "Candelas"]}, Quantity[2, "Microns"]}]QuantityMagnitude threads arguments:
QuantityMagnitude[{Quantity[1, "Hours"], Quantity[1, "Seconds"]}, {"Days", "Weeks"}]QuantityMagnitude returns the MixedMagnitude specification of a mixed Quantity:
Quantity[MixedMagnitude[{1, 80}], MixedUnit[{"Meters", "Centimeters"}]]QuantityMagnitude[%]QuantityMagnitude[Quantity[MixedMagnitude[{5, 10}], MixedUnit[{"Feet", "Inches"}]]]QuantityMagnitude will automatically attempt to interpret an unknown unit string:
QuantityMagnitude[Quantity[100, "Yards"], "Meterss"]When the target unit is specified as a Quantity object, its magnitude will be ignored:
QuantityMagnitude[Quantity[100, "Yards"],
Quantity[100, "Meters"]]In its two-argument form, the first argument of QuantityMagnitude can also be a unit string:
QuantityMagnitude["UniverseAge", "Seconds"]Text
