WooCommerce: Stock Quantity Suffix e.g. “sq. in.”, “Kg”, “boxes”, etc.

Each WooCommerce business is different, which means customization is required to adapt the store to unique specifications.

A clear example is the stock quantity. Not all stores can display the standard notice “11 in stock”. The display could change to “11 Kg in stock” if stock is based on weight. Or maybe “11 boxes in stock” or “11 pairs in stock” in case the package description is useful UX-wise. Also, “11 m³ in stock” if the business sells volumes.

Either way, this is a nice trick to display a “stock quantity suffix” in your WooCommerce Single Product Page. Enjoy!

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (delete "?>" if you have it there). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"
