# measurement(width:usage:hidesScaleName:numberFormatStyle:)

Returns a format style to format temperature units.

## Declaration

```swift
static func measurement(width: Measurement<UnitTemperature>.FormatStyle.UnitWidth = .abbreviated, usage: MeasurementFormatUnitUsage<UnitTemperature> = .general, hidesScaleName: Bool = false, numberFormatStyle: FloatingPointFormatStyle<Double>? = nil) -> Self where Self == Measurement<UnitTemperature>.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

Return Value A format style that formats measurements according to the given parameters.

## Discussion

Discussion Use this static method when the call point allows the use of Measurement.FormatStyle and the value type is Measurement<UnitTemperature>. You typically do this when calling the formatted(_:) method of Measurement. The following example creates an array of Measurement values that represent body temperatures from a human patient. It then uses formatted(_:) and the format style provided by this method to format the distances. The style specifies the person usage to clarify that the temperatures refer to a person’s body temperature, as opposed to other uses like weather. 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"]
