Question

Create a GUI application that can be is used to convert a distance unit in miles into its corresponding units in kilometer, meter, inches and centimeter. When a user enters a mile value in a text field and followed by pressing a button, its equivalent values in unit of kilometer, meter, inches and centimeter will be displayed in the corresponding text fields. If the user enters the value of miles that is less or equals to zero, a dialogue error message that contains a message “The value must be greater than zero” will be displayed.
The formula for each of unit conversion is as follows:
1 mile = 2.5 km
1 km = 1000 m
1 meter = 60 inches
1 inches = 2.54 m

Answer 1

1 mile = 1.609344 km

1km = 1000 m

1 m = 39.37007874 in

1 in = 2.54 cm = 25.4 mm

1 cm = 0.3937007874 in

Answer 2

1 meter = 39.3700787 inches

1 mile = 1.609344 kilometers

1 km = 0.621371192 miles



I see you also questioned the ratio factors. The ones I posted are the ones I used to convert with.
