WooCommerce product weight unit

Today, you will learn how to go beyond WooCommerce options and change the default unit of measure (weight) for your product.

Change weight unit in WooCommerce

In the article, you will learn 3 solutions for showing WooCommerce product weight depending on your needs.

1️⃣ First, you may want to simply show the information about the product weight. Here you can set and use standard WooCommerce settings to define the weight unit (solution 1).

2️⃣ Also, you may add a new weight unit for WooCommerce products with a few lines of code (solution 2). Of course, if you need a new weight unit.

3️⃣ Finally, if the informational purposes are not enough, you may use a plugin to change the weight unit, set the new unit of measure, and sell products by weight (solution 3).

So, let’s see each solution closer!

Solution 1: by the built-in option

By default, WooCommerce lets you show the product weight on the product page.

First, you may simply define the product WooCommerce weight that will be visible on the product page.

1. Go to the product Edit screen -> Product Data section -> Shipping tab and enter the product weight.
   
2. If you want to change the weight unit for all WooCommerce products, go to WooCommerce -> Settings -> Products -> General tab. Here you can change the weight and dimensions unit for the WooCommerce product.
   By default, you can choose kg, g, lbs, or oz for the weight unit (and m, cm, mm, in, or yd for dimensions). Please note that this setting will work for all products!
   
3. The information about the product weight will appear on the product page in the Additional Information section. In the example below, I've changed the weight unit to grams.
   

In that solution, your customer will see more information about the product. But that’s not all, of course.

Because you may want to calculate the shipping cost based on the product weight later on (with a custom code, or a plugin)! That will give you more flexibility with your shipping costs.

Solution 2: programmatically

The first solution may suffice, but how to choose the product weight unit that is not there? It’s quite simple. You can add a new weight unit with this small code (add this to the functions.php file of your WordPress theme or use the code in a separate plugin).

Then, you will be able to change the WooCommerce weight unit for a custom one.

That solution will be obviously useful if you sell products in mg, pallets, or packages.

The new weight unit will then appear on the product page.

⭐Solution 3: with a free plugin⭐

Now, how about selling your products based on the weight unit itself?

In that case, the above solutions will not be enough. On the other hand, you may use a free plugin to set the product’s new unit of measurement (including weight units).

So, in other words, you will be able to sell a product based on a new unit of measure.

Imagine using the plugin and its features in your store!
