Length Converter

[xxxlizzyxxx]

Hey there I am trying to create a simple converter for length like cm and m etc, to put onto my simple site that I have started to build, I just don't know how to start it off or what making sure that the code doesnt look like I have copied and pasted it as its for an assignment in uni. I hope someone can help me!!

I would create a set of static methods in a class, naming everything so that it's obvious what each method does, e.g.:

<?php

class LengthCoverter
{
   const CM_PER_INCH = 2.54;
   public static function cmToInches($length)
   {
      return $length / self::CM_PER_INCH;
   }
   public static function inchesToCm($length)
   {
      return $length * self::CM_PER_INCH;
   }
}

// Sample usage:
echo "12 inches = ".LengthCoverter::inchesToCm(12)." cm.<br />\n";
echo "7.62 cm = ".LengthCoverter::cmToInches(7.62)." inches.";

Ok thanks for that, quick question if I was wanting to do it as I wanted to ask the user what value they wanted converted in a form how would I go about doing that?
