Customise WooT Measurement Price Calculator plugin and WooC emails

Hi, Currently we have our shop set up to show products and place orders in one page using ( [login to view URL] ), we're bypassing the payment so the orders are placed immediately (will be placed by shop owners not plugin). What we've done additionally was show the weight (pack size) and an attribute (units per package). We also needed to be able to select the unit of weight per product i.e. g, Kg, ml, L ; so we've implemented the WooThemes Measurement Price Calculator ( [login to view URL] ) as that allowed us to enter the weight (g, Kg) and volume (ml, L) but it couldn't allow changing from g to Kg per product and ml to L per product, it only added the choice in the settings (you could still enter either but if it was set to 'g' you couldn't change it to 'Kg' for a specific product for example). We were hoping that we could just use the plugin's hook to grab the weight and volume and show that on the frontend but we weren't able to due to so, the weight appears but not the volume. We also need to show the weight/volume in the emails sent to the customer and admin (we managed to show only the weight but not the volume). Hopefully that outlined the issue, we need someone to implement the weight and volume from the plugin to show on the order page and in emails. We also need the choice of choosing between g, Kg, ml, L or perhaps as a workaround from choosing between g and Kg, ml and L; would it be possible to add some code that changes 1200g to 1.2Kg and 1800ml to 1.8L if that's what is entered? Thanks for your time. Regards, Stan
