Create a new instance of the UnitConverterUNECERec20.js class as follows:

var units=new UnitConverterUNECERec20();

Convert quantitative value from one unit of measure to a different specified unit

var units=new UnitConverterUNECERec20();

var result=convert({"FAH",212},"CEL");

// convert 212 degrees Fahrenheit to degrees Celsius gives result=100

Find related units for the same physical property

var units=new UnitConverterUNECERec20();

var relatedUnits=relatedUnits("ATM");

// find related units for "ATM" (atmospheres) 
// returns other units of pressure, ["ATM","BAR","HN","J89","MBR","PAL","PS"]

Convert quantitative value from one unit of measure to multiple units of the same physical property

var units=new UnitConverterUNECERec20();

var result=multiconvert({"CEL",100});

// convert 100 degrees Celsius into other temperature units 
// result:  {"KEL":373.15,"FAH":211.99999999999997,"CEL":100,"A48":671.67}
