Field Detail

SI

public static final DimensionlessUnit SI

The SI unit for a dimensionless unit is "1" or N/A.

Method Detail

getStandardUnit

public DimensionlessUnit getStandardUnit()

Specified by:

getStandardUnit in class Unit<DimensionlessUnit>

Returns:

the SI standard unit for this unit, or the de facto standard unit if SI is not available

getSICoefficientsString

public String getSICoefficientsString()

Specified by:

getSICoefficientsString in class Unit<DimensionlessUnit>

Returns:

the SI standard coefficients for this unit, e.g., kgm/s2 or m-2s2A or m^-2.s^2.A or m^-2s^2A (not necessarily normalized)

equalsIgnoreNaming

public boolean equalsIgnoreNaming(Object obj)

Test if two units are the same, except for the name and abbreviation. This means for instance that for the MassUnits METRIC_TON and MEGAGRAM (both 1000 kg) equals(...) will yield false, but equalsIgnoreNaming will yield true.

Specified by:

equalsIgnoreNaming in class Unit<DimensionlessUnit>

Parameters:

obj - Object; the object to compare with

Returns:

true if the two units are the same numerically, except for the naming and/or abbreviation
