getConverterTo method
Returns a converter of numeric values from this unit to another unit.
Implementation

var thatSystemUnit = that.standardUnit;
if (thisSystemUnit == thatSystemUnit) {
return that.toStandardUnit().inverse.concatenate(toStandardUnit());
}
// Use dimensional transforms.
throw UnimplementedError();
