Class TemperatureUnit

java.lang.Object

manifold.science.measures.TemperatureUnit

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<TemperatureUnit>, ComparableUsing<TemperatureUnit>, Dimension<TemperatureUnit>, Unit<Temperature,TemperatureUnit>

public final class TemperatureUnit
extends java.lang.Object
implements Unit<Temperature,TemperatureUnit>

The kelvin is the SI unit of thermodynamic temperature. All instances of TemperatureUnit convert to and from degrees Kelvin.

Since May 2019, the kelvin and degree Celsius have been defined by taking a fixed numerical value of the Boltzmann constant, k or kB. This change in definition acknowledges that temperature is fundamentally a measure of the average energy of molecular motion. (ref. npl.co.uk)

Constructor Detail

TemperatureUnit

public TemperatureUnit(java.util.function.Function<Rational,Rational> toK,
                       java.util.function.Function<Rational,Rational> fromK,
                       java.lang.String name,

Method Detail

get

public static TemperatureUnit get(java.util.function.Function<Rational,Rational> toK,
                                  java.util.function.Function<Rational,Rational> fromK,
                                  java.lang.String name,
                                  java.lang.String symbol)

Get or create a unit using the toK and fromK conversion functions. The specified unit is cached based on the name and symbol and will be returned for subsequent calls to this method if name and symbol match.

Parameters:

toK - A function to convert the named unit to degrees Kelvin.

fromK - A function to convert from degrees Kelvin to degrees of the named unit.

name - The standard full name of the unit e.g., "Celsius".

symbol - The standard symbol used for the unit e.g., "°C".

Returns:

The specified unit.

makeDimension

public Temperature makeDimension(java.lang.Number amount)

Specified by:

makeDimension in interface Unit<Temperature,TemperatureUnit>

getName

public java.lang.String getName()

Specified by:

getName in interface Unit<Temperature,TemperatureUnit>

Returns:

The name of this unit, such as "Meter" or "Pound".

getSymbol

public java.lang.String getSymbol()

Specified by:

getSymbol in interface Unit<Temperature,TemperatureUnit>

Returns:

The symbol for this unit. For example, SI units define "Meter" to have symbol "m".

toBaseUnits

public Rational toBaseUnits(Rational myUnits)

Specified by:

toBaseUnits in interface Unit<Temperature,TemperatureUnit>

Parameters:

myUnits - A magnitude of these units to convert to base units.

Returns:

The theseUnits converted to the base units of this unit type.

toNumber

public Rational toNumber()

Specified by:

toNumber in interface Dimension<TemperatureUnit>

Returns:

the value for this dimension instance.
