# measurement(width:usage:hidesScaleName:numberFormatStyle:) Returns a format style to format temperature units. ``` static func measurement(width: Measurement.FormatStyle.UnitWidth = .abbreviated, usage: MeasurementFormatUnitUsage = .general, hidesScaleName: Bool = false, numberFormatStyle: FloatingPointFormatStyle? = nil) -> Self where Self == Measurement.FormatStyle ``` ## Parameters `width` The width — such as full names or abbreviations — with which to present units. `usage` The contextual usage of the measurement unit, such as whether a temperature applies to a person or to the weather. `hidesScaleName` A Boolean value that directs the formatter to hide the name of the scale (Kelvin, degrees Celsius, or degrees Fahrenheit). Defaults to `false`. `numberFormatStyle` The format style with which to format the numeric part of the temperature. ## Return Value A format style that formats measurements according to the given parameters. ## Discussion Use this static method when the call point allows the use of [`Measurement.FormatStyle`](/documentation/Foundation/Measurement/FormatStyle) and the value type is `Measurement`. You typically do this when calling the [`formatted(_:)`](/documentation/Foundation/Measurement/formatted(_:)) method of [`Measurement`](/documentation/Foundation/Measurement). The following example creates an array of [`Measurement`](/documentation/Foundation/Measurement) values that represent body temperatures from a human patient. It then uses [`formatted(_:)`](/documentation/Foundation/Measurement/formatted(_:)) and the format style provided by this method to format the distances. The style specifies the [`person`](/documentation/Foundation/MeasurementFormatUnitUsage/person-4ifk7) usage to clarify that the temperatures refer to a person’s body temperature, as opposed to other uses like weather. ```swift let rawTemparatures: [Double] = [36.4, 36.6, 37.0, 36.9, 36.7] let temperatures = rawTemparatures.map { Measurement(value: $0, unit: UnitTemperature.celsius) } let formattedTemperatures = temperatures.map { $0.formatted( .measurement(width: .abbreviated, usage: .person, hidesScaleName: false, numberFormatStyle: .number)) } // ["36.4°C", "36.6°C", "37°C", "36.9°C", "36.7°C"] ``` --- Copyright © 2026 Apple Inc.
