The Unidata UDUNITS Package

Background

The Unidata units library supports conversion of unit specifications between formatted and binary forms, arithmetic manipulation of unit specifications, and conversion of values between compatible scales of measurement. The package (as standalone) has interfaces to C Language and FORTRAN language.
However, it forms also part of the NetCDF-Java 2.2 Library (which is a Java interface to NetCDF files) specifically, ucar.nc2 and ucar.units packages.

DelftTools.Units

The project provides system of unit, units and converters interfaces. By default, the used system of units is SI (International System of Units). Imperial units system is the other possible option.

The Interfaces defined in DelftTools.Units project are shown below:

Examples

Simple unit
  
IDimension lengthDimansion = new Dimension("Length", "L");

IUnit meter = new Unit("meter", "m", lengthDimansion);
Transformed Unit
/// TransformedUnit = Multiplier . BaseUnit^Power + Offset
        
ITransformedUnit squareMeter = new TransformedUnit(SI.BaseUnits.Meter, 1, 2, 0);

Assert.AreEqual(1,squareMeter.Multiplier);

Assert.AreEqual(2,squareMeter.Power);

Assert.AreEqual(0, squareMeter.Offset);

Assert.AreEqual("m^2",squareMeter.Symbol);

Assert.AreEqual("L^2",squareMeter.Dimension.Symbol);
Product Unit
/// ProductUnit = ProductUnit1 * ProductUnit2 * ... * ProductUnitN

IUnit meter = new Unit("meter", "m", SI.BaseDimensions.Length);
            
IUnit kilogram = new Unit("kilogram", "kg", SI.BaseDimensions.Mass);
            
IUnit second = new Unit("second", "s", SI.BaseDimensions.Time);
           
IProductUnit forceUnit = new ProductUnit("newton");
            
forceUnit.ProductUnits.Add(meter);
            
forceUnit.ProductUnits.Add(kilogram);
            
forceUnit.ProductUnits.Add(new TransformedUnit(second, 1.0, -2.0, 0.0));
            
Assert.AreEqual("L.M.T^-2", forceUnit.Dimension.Symbol);
         
Assert.AreEqual("m.kg.s^-2", forceUnit.Symbol);
