PHP Unit converter

Here's my unit converter based on the extra credit on the new PHP Basics course.

I didn't know how to set up a php console like in Workspaces so I put it on a web page. I need to improve the responsive web design but I'll do that later. http://www.jonniegrieve.co.uk/jg-lab.co.uk/phpbasics-2016/unit.php

    <?php

    /*Store Values*/

    //pounds,kg, miles, kilos
    $pounds = 140;
    $kilograms = 140;
    $miles = 2.5;
    $kilometers = 2.5;
    $fahrenheit = 10;
    $celsius = 10;


    /*Conversion values*/

    //floating point value for the pound to kilogram conversion
    $lb_to_kg = 0.453592;
    //reverse calculation;
    $kg_to_lb = 2.20462;
    //floating point value for miles to kilometor calculation.
    $mile_to_km  = 4.02336;
    //reverse calculation
    $km_to_mile = 1.55343;
    //integer value for fahrenheight to celsius
    $fh_to_cs = 10;
    //reverse calculation
    $cs_to_fh = 50;

    //Make the conversion calculations
    $convertKilograms = $pounds * $lb_to_kg;
    $convertPounds = $kilograms * $kg_to_lb;

    $convertKilometers = $miles * $mile_to_km;
    $convertMiles = $kilometers * $km_to_mile;

    $convertFahrenheit = $celsius * $cs_to_fh;
    $convertCelsius = $fahrenheit * $fh_to_cs; 


    /*display the pounds to kilograms
    echo "<p>Weight: " . $pounds . " lb = " . $convertKilograms . "kg</p>";
