+See [Samples/UnitConverter.Wpf](https://github.com/angularsen/UnitsNet/tree/master/Samples/UnitConverter.Wpf) for source code.
 
 This example shows how you can create a dynamic unit converter, where the user selects the quantity to convert, such as `Length` or `Mass`, then selects to convert from `Meter` to `Centimeter` and types in a value for how many meters.
 
+NOTE: There are still some limitations in the library that requires reflection to enumerate units for quantity and getting the abbreviation for a unit, when we want to dynamically enumerate and convert between units.
+
+### <a name="example-app-hardcoded"></a>Example: Creating a unit converter app with hard coded quantities
+
+If you can live with hard coding what quantities to convert between, then the following code snippet shows you one way to go about it:
+
 ```C#
 // Get quantities for populating quantity UI selector
 QuantityType[] quantityTypes = Enum.GetValues(typeof(QuantityType)).Cast<QuantityType>().ToArray();
 
 // If Length is selected, get length units for populating from/to UI selectors
 LengthUnit[] lengthUnits = Length.Units;
 
-// Perform conversion by using .ToString() on the selected units
+// Perform conversion using input value and selected from/to units
+double inputValue; // Obtain from textbox
+LengthUnit fromUnit, toUnit; // Obtain from ListBox selections
+double resultValue = Length.From(inputValue, fromUnit).As(toUnit);
+
+// Alternatively, you can also convert using string representations of units
 double centimeters = UnitConverter.ConvertByName(5, "Length", "Meter", "Centimeter"); // 500
 double centimeters2 = UnitConverter.ConvertByAbbreviation(5, "Length", "m", "cm"); // 500
 ```

+## Unit Converter WPF Sample App
+
+This is a simple sample showing how UnitsNet can be used to create a generic unit converter, using all the quantities and units available in the UnitsNet library.
+
+![image](https://user-images.githubusercontent.com/787816/34920961-9b697004-f97b-11e7-9e9a-51ff7142969b.png)
+
+It allows you to convert a value from one unit to another, by first selecting the quantity (`Length`), then selecting the from/to units (`Meter` to `Centimeter`) and finally typing the numeric value (`15.3`).
+The resulting value (`1530`) is computed instantly and reacts to whenever the numeric value or the from/to unit selection changes.
+
+This sample also highlights a limitation in the library that requires reflection in order to enumerate units for a selected quantity and to get the abbreviation for a unit, since the library does not provide a generic means to retrieve these without referencing types like `Length` and `LengthUnit` directly. There is definitely room for improvement in the library here.
