Task 1 - Conversion

The objective of this program is to develop a graphical user interface that will convert the entered number which is in Fahrenheit to its equivalent value in Celsius . Aside from this , conversions like from Inches to Miles and Quartz to Cubic Feet is also included in the program . All screenshots are shown in the succeeding figures below

The development of a program which basically covers on various conversion types takes only a number of processes . The conversions involve are Fahrenheit to Celsius , Inches to Miles

and Quartz to Cubic Feet . For Fahrenheit to Celsius , a value in Fahrenheit is subtracted by 32 and multiplied by 5 /9 . For inches to miles , a number in inches is divided by 12 since there are 12 inches in 1 foot and the result is further divided by 5280 since there are 5280 feet in 1 mile . A number expressed in quartz is multiplied by 0 .25 since there are 0 .25 gallons in 1 quart . The result is further multiplied by 0 .13 since there are 0 .13 cubic feet in 1 gallon . These are the processes that work behind the OK button of the form . All these are implemented in the correct manner , thus , coming up with the expected output

The development of the program includes the utilization of the different tools in Visual Studio .Net . It takes only 2 hours to finish the working program . The design of the program involves the tools in ASP .Net such as labels , textboxes and command buttons as shown in the figures below

The working progress of the program is shown below

The next figure shows the code behind the graphical user interface

The program is coded using C ASP .NET . The program code is as follows
