Java Program to Convert Kilometer Per Hour to Feet Per Second

In the previous article we have discussed about Java Program to Convert Feet Per Second to Meters Per Second

In this article we are going to see how to convert kilometer per hour to feet per second by using Java programming language.

Java Program to Convert Kilometer Per Hour to Feet Per Second

Kilometer is used as a unit to measure length of long distance like road distance and Feet is used as a unit of length to measure smaller length.

Before jumping into the program, first let’s know the relation between kilometer per hour and feet per second.

1 Kilometer Per Hour = 0.911344 Feet Per Second

Then the formula to convert kilometer per hour to feet per second is

Feet Per Second =  Kilometer Per Hour * 0.911344

Let’s see different ways to convert kilometer per hour to feet per second.

By Using Static Input Value
By Using User Input Value
By Using User Defined Method

Method-1: Java Program to Convert Kilometer Per Hour to Feet Per Second By Using Static Input Value

Approach:

Declare a double variable say ‘kilometerPerHour‘ and initialize it’s value.
Then convert kilometer per hour to feet per second by using formula.
Print the result.

Program:

public class Main
{
    public static void main(String[] args) 
    {
        //declared value of kilometer per hour
        double kilometerPerHour=1;
        //converting kilometer per hour to feet per second
        double feetPerSecond=kilometerPerHour * 0.911344;
        //printing result
        System.out.println(kilometerPerHour+" kilometer per hour is equal to "+feetPerSecond+" feet per second");
    }
}

Output:

1.0 kilometer per hour is equal to 0.911344 feet per second

Method-2: Java Program to Convert Kilometer Per Hour to Feet Per Second By Using User Input Value

Approach:

Take the value of double variable ‘kilometerPerhour‘ as user input by using Scanner class.
Then convert kilometer per hour to feet per second by using formula.
Print the result.

Program:

import java.util.*;
public class Main
{
    public static void main(String[] args) 
    {
        Scanner sc=new Scanner(System.in);
        System.out.print("Enter the value of kilometer per hour: ");
        //declared double variable kilometerPerHour 
        //and taking it's value as user input
        double kilometerPerHour=sc.nextDouble();
        //converting kilometer per hour to feet per second
        double feetPerSecond=kilometerPerHour * 0.911344;
        //printing result
        System.out.println(kilometerPerHour+" kilometer per hour is equal to "+feetPerSecond+" feet per second");
    }
}

Output:

Enter the value of kilometer per hour: 40
40.0 kilometer per hour is equal to 36.45376 feet per second

Method-3: Java Program to Convert Kilometer Per Hour to Feet Per Second By Using User Defined Method

Approach:

Take the value of double variable ‘kilometerPerHour‘ as user input by using Scanner class.
Then call a user defined method say convertValue() by passing kilometerPerHour value as parameter.
Inside method convert kilometer per hour to feet per second by using formula.
Print the result.

Program:

import java.util.*;
public class Main
{
    public static void main(String[] args) 
    {
        Scanner sc=new Scanner(System.in);
        System.out.print("Enter the value of kilometer per hour: ");
        //declared double variable kilometerPerHour 
        //and taking it's value as user input
        double kilometerPerHour=sc.nextDouble();
        //calling user defined method converValue()
        convertValue(kilometerPerHour);
    }
    
    //convertValue() user defined method 
    public static void convertValue(double kilometerPerHour)
    {
        //converting kilometer per hour to feet per second
        double feetPerSecond=kilometerPerHour * 0.911344;
        //printing result
        System.out.println(kilometerPerHour+" kilometer per hour is equal to "+feetPerSecond+" feet per second");
    }
}

Output:

Enter the value of kilometer per hour: 25
25.0 kilometer per hour is equal to 22.7836 feet per second
