Shopify Liquid Code to display Variations in specific Format

Hi

https://hilacreations.com/products/dialogue-1

See this page. The Variations are displayed by In./Cm. Button.

There is separator used “/“ while creating variants .

In frontend it is displayed either in inches or in centimetres .

It is not down by an app but custom code .

I want it to be done for another Shopify store .

Thanks
