Question
I need to make a UnitConversionApplication that includes the ability of converting Centimeters to Inches, Centimeters to Feet, Meters to Yards, and Kilometers to Miles by adding additional menu items. The additional conversions will have their own methods as well. The formulas are the opposite, instead of multiplying you will divide.
Enter a number to convert: 10
Convert:
1. Inches to Centimeters 5. Centimeters to Inches
2. Feet to Centimeters 6. Centimeters to Feet
3. Yards to Meters 7. Meters to Yards
4. Miles to Kilometers 8. Kilometers to Miles
Enter your choice: 5
10 centimeters equals 3.93 inches.
