The weight of earth is estimated at 6,000,000,000,000,000,000,000,000 kgs. Write a program which calculates and prints earth's weight in kgs, pounds, Imperial tons and US tons accurate to one decimal place. You must not hard code calculated values in the print statement. Instead, use properly declared variables and perform calculations in your program. No String data types or exponential notation (E) allowed. [10 points]
