Flowchart to convert distance in Kilometers to Miles

Overview

In this tutorial, we will learn to design a Flowgorithm flowchart to convert distance in kilometers to miles.

Problem Statement

Draw a flowchart that asks the user to enter the distance in Kilometers. The flowchart computes the distance in Miles using the following formula:

Miles = 0.62137 × Kilometers

Flowchart Output

The program should display the distance in Kilometers and Miles. The output requirement is that the flowchart should only display three digits after the decimal point for both kilometers and miles output.

The desired flowchart output is as follows:

Distance:
Kilometers = 100

Miles = 62.137

Flowchart

Steps to design the flowchart are:

Launch Flowgorithm Flowchart tool
Save the flowchart with a name in the .fprg file
Add a comment with a Flowchart description
Declare two variables: Kilometers, Miles
Prompt user to enter the distance in kilometers
Store the user input into the Kilometers variable
Compute and process the user input
Display the desired output to the computer screen

Kilometers to Miles Flowchart Flowgorithm

Sample Output

Save the flowchart and run it with sample input.

Verify the flowchart output.

Convert Distance Kilometers to Miles

Test Case 1

Enter distance in Kilometers:=
100
Distance:
Kilometers = 100
Miles = 62.137

Test Case 2

Let’s consider the following input to the flowchart. This makes the test case is a fail.

Enter distance in Kilometers:=
10.568896667
Distance:
Kilometers = 10.568896667
Miles = 6.56719532197379

The output displays more than three decimal places in the output. We need to fix this bug in the flowchart. We can use the ToFixed() inbuilt function to display a certain number of digits after the decimal point.
