The above calculator is fully functional, so if you want to use it yourself, go ahead. The instructions below are for webmasters which want to use this calculator on their websites for free.

Weight Loss Calculator Installation

Once downloaded the above software, unzip it and upload it somewhere in your web host. It's just one single PHP script so all you need to do is to upload it. Then put the following PHP code in your web page:

<?php
require("weight-loss-calculator.php");
?>

That's all! Note that if you put the calculator in a folder, you need to give the relative path to it.

The software validates the user input with javascript instantly. It also converts pounds to kilos, inches to centimeters and vice versa so the end user of this weight loss calculator can type the numbers she is most used to.

This script is completely free and you can do everything you want in it. There are no obligations at all. There is a link to this site at the bottom, but if you wish to remove it, that's ok (We will appreciate if you leave it there though).

Do you need a quality and affordable web host for your projects? I host many of my sites on HostGator - they give unlimited domains, unlimited disk space and unlimited bandwidth for less than $10 monthly.
