A problem

You are working on a building project with a measuring device which only reports inches. Finding it difficult to deal with these measurements, you have decided to write an app which converts inches to yards, feet and inches.

Your program should prompt the user for a measurement given in inches. You program should then compute the measurement in yards, feet and inches. Finally, you should provide a check by converting your values back to inches.

Your output should conform to the following example:

Please enter a measurement in inches: 51
51 inches is the same as:
   Yards:     1
   Feet:      1
   Inches:    3

Check:
1 Yards 1 Feet and 3 inches is 51 inches.

An Algorithm

Problem description: Given a measurement in inches, convert this to inches, feet and yards.

Algorithm

Get the distance in inches
Using div and mod, convert inches to inches and feet
Using div and mod, convert feet to feet and yards
Compute total inches based on inches feet and yards
print the results.

Note that for any conversion from smaller to larger:
     value in  smaller / CONVERSION_FACTOR = value in larger
     value in  smaller % CONVERSION_FACTOR = left over in smaller

Example computation

Measurement in inches: 51
Convert to feet and inches:
    51 / 12 = 4 this is feet for now
    51 % 12 = 3 this is final inches
Convert to yards and feet
     4 / 3 = 1  this is yards
     4 % 3 = 1  this is feet
Compute the total
     1 * 3 * 12 + 1 * 12 + 3 = 51 check
Print the results.

Questions?
1. Will there be a need to compute chains, furlongs miles and leagues?
2. Will there be a need to use a rational system like the metric system?
