i dont know if im explaining this corretly in my other posts

I have created a template, I am a web developer so Ihave no issues with changing code.

Though I would like to know how to do the following:

If i add a product in the admin, i set a price. Lets say the product is Sirloin Steak, at £10.00

I have another product called Braising Steak but this time i want the price to be £10.00/Per Kg

How would I have the system display "Per Kg" after the price, for that individual product? All i can think of is adding an extra field in the products table of the database and changing a bunch of code to allow it to work..

Is there a quicker way?
