Question

Write a program that converts grams to pounds. (One pound equals 453.592 grams.) Read the grams value from the user as a floating point value.

Answer 1

Answer:

import java.util.Scanner;

public class TestClock {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter Value in grams");

       double grams = in.nextDouble();

       double pounds = 453.592*grams;

       System.out.println(grams+" grams is equal to "+pounds+" pounds");

   }

}

Explanation:

1. Import the Scanner Class to receive user input
2. Save the user input in a variable
3. Use the conversion 1 pound = 453.592 grams to calculate the equivalent grams
4. Output the the value of pounds calculated

Answer 2

The program that converts grams to pounds is as follows;

def grams_to_pounds(x):

  weight_in_pounds = x / 453.592

  return weight_in_pounds

w1 = grams_to_pounds(500)

w2 = grams_to_pounds(1000)

w3 = grams_to_pounds(2000)

print(w1)

print(w2)

print(w3)

Code explanation

• A function grams_to_pounds is declared with an argument x . The argument x is the mass in grams.
• The variable  weight_in_pounds is use to store the value of when the mass in grams is divided by 453.592
• Finally, we call our function with it parameter, using the variables w1, w2 and w3 to store it.
• The print statement is use to print the variables.
