Use KiloConverter.java

1. Create another converter to convert centimeters to inches (1 cm = 0.393701 inch)

2. Create another converter to convert Celsius to Fahrenheit. °C to °F: Multiply by 9, then divide by 5, then add 32

3. Create another converter to convert Fahrenheit to Celsius. °F to °C: Deduct 32, then multiply by 5, then divide by 9
