Assembly:	Sirenix.Utilities.Editor

public static class UnitNumberUtility

Tools for converting between units, for example, converting from inches to meters.

Inheritance

System.Object
UnitNumberUtility

Methods

AddCustomUnit(String, String[], UnitCategory, Decimal)

Adds a custom unit to the UnitNumberUtility, that can also be used with the . Call this using InitializeOnLoad or InitializeOnLoadMethod.

public static void AddCustomUnit(string name, string[] symbols, UnitCategory unitCategory, decimal multiplier)

Parameters

System.String	name	The name of the unit. Duplicate names are not allowed.
System.String[]	symbols	Symbols used for the unit. First value in the array will be used as the primary symbol. Atleast 1 value required. Duplicate symbols are not allowed within the same category.
UnitCategory	unitCategory	The category of the unit. Units can only be converted to another of the same category. Custom categories are allowed.
System.Decimal	multiplier	The multiplier to convert the unit from the base value. For example, meters are the base unit of the distance category, therefore centimeters have a multipler of 100.

AddCustomUnit(String, String[], UnitCategory, Func<Decimal, Decimal>, Func<Decimal, Decimal>)

Adds a custom unit to the UnitNumberUtility, that can also be used with the . This overload allows for custom conversion methods but, if possible, the multiplier overloads should be prefered. Call this using InitializeOnLoad or InitializeOnLoadMethod.

public static void AddCustomUnit(string name, string[] symbols, UnitCategory unitCategory, Func<decimal, decimal> convertToBase, Func<decimal, decimal> convertFromBase)

Parameters

System.String	name	The name of the unit. Duplicate names are not allowed.
System.String[]	symbols	Symbols used for the unit. First value in the array will be used as the primary symbol. Atleast 1 value required. Duplicate symbols are not allowed within the same category.
UnitCategory	unitCategory	The category of the unit. Units can only be converted to another of the same category. Custom categories are allowed.
System.Func<System.Decimal, System.Decimal>	convertToBase	Method for converting a given value of the custom unit to the base unit. For example, for centimeter, use: `x => x / 100m;`.
System.Func<System.Decimal, System.Decimal>	convertFromBase	Method for converting a given value of the base unit to the custom unit. For example, for centimeter, use: `x => x * 100m;`.

AddCustomUnit(String, String[], String, Decimal)

System.String	unitCategory	The category of the unit. Units can only be converted to another of the same category. Custom categories are allowed.
System.Decimal	multiplier	The multiplier to convert the unit from the base value. For example, meters are the base unit of the distance category, therefore centimeters have a multipler of 100.
