[SOLVED] Cost per weight calc

[Canman2005]

Hi all

 

Wondering if someone can help.

 

I have a few variables, they are

 

//weight in grams

$weight = '600';

$price = '299.99';

 

//weight in kilograms (kg)

$weight = '45.2';

$price = '699.21';

 

I need to do a calculation to work out the cost per kilogram (kg) for both my grams variables and also the kilogram (kg) variables

 

What would be the best way to find out the cost per kilogram (kg)

 

Any help would be ace

 

thanks

<?php
//weight in grams (A)
$weightA = '600';
$priceA = '299.99';

//weight in kilograms (kg) (B)
$weightB = '45.2';
$priceB = '699.21';

// cost for a
$costPerKGA =  $priceA / ($weightA * 1000);

// cost for b
$costPerKGB = $priceB / $weightB;

I think it should be ($weightA / 1000), n3ight.
