Algorithm

1. Write an algorithm (Flowchart or Pseudocode) which inputs a length in inches, and outputs its equivalent in centimeters (1 inch = 2.54 centimeters) 


2. Write an algorithm (Flowchart or Pseudocode) to input temperature in Fahrenheit and output the corresponding temperature in Centigrade. The formula for conversion is as follows.

C= 5/9 x (F - 32) 

3. Write  algorithm (Flowchart or Pseudocode) to find the perimeter and area of a rectangle
The perimeter and area of the rectangle are given by the following formulas:
  perimeter = 2 * (length + width)
  area = length * width

 4. (Finding the number of minutes and  hours) Write a program that prompts the users to enter a number of seconds (e.g 1000000) and displays the equivalent numbers of hours and equivalents numbers of minutes.
Here is a sample run:
Enter the number of seconds :1000000
1000000 seconds = 16666.67 minutes
1000000 seconds = 277.78 hours

5. Write an algorithm (Flowchart and Pseudocode)  that accepts a student’s numerical grade, converts the numerical grade to an equivalent letter grade, and displays the letter grade.

A student’s letter grade is calculated according to the following schedule:

Numerical grade	Letter grade
90-100	A
80-89	B
70-79	C
60-69	D
0-59	F

Java Program 
1.
import java.util.Scanner;
public class cuba2 {
   
    public static void main(String[] args) {
      
        Scanner input = new Scanner(System.in);
        int inch;
        double cm;
        inch =input.nextInt();
        cm= inch * 2.54;
        System.out.println(cm);
      
    }
}
