The WooCommerce Price Per Unit Plugin helps you sell your product when it's important for your customers to know how much it costs in units of weight. The plugin helps you find the value in units of weight by taking the price of a product and dividing that price by its weight to sell the product to a customer. It works similarly to floating instruments but is easier to manage because you only need to enter a price once and the option price is calculated automatically. You can also add text after the recalculated price (eg "/kg"). The price will only be recalculated if you have a set weight on the item.
