WooCommerce Shipping from the United States -Product Weight Units in Pounds

When using the WooCommerce UPS Shipping Plugin, it’s important to use the correct units for product weight and dimensions. These should match your store’s location and UPS requirements. Using incorrect units can cause errors or lead to unexpected shipping rates.

In this short guide, we’ll show you how to choose the correct measurement units. This will help ensure accurate rate calculation when using the plugin. Read on to learn more through a real conversation between a customer and the PluginHive support team.

Customer:

I believe that there is an issue in that all of the store products are entered in kilograms, and the client is shipping out of California and UPS is returning rates for thousands of dollars for shipping a handful of 0.01 kg items. We have it set for kg vs lbs but even then, in UPS, it complains, “This measurement system is not valid for the selected country.”

PluginHive Support:

The error message “This measurement system is not valid for the selected country” appears when an incorrect measurement unit is selected in the plugin settings.

Since your store is based in the United States, you need to select the Imperial system, which uses weight in pounds (lb). Please update the plugin settings accordingly.

Also, please make sure that you have configured the same unit of measurement under WooCommerce settings as well.

After making the changes, check the shipping rates again.

If you still notice a mismatch in rates, several factors could be responsible. These include the weight and dimensions of the product, packaging type, special services selected, and the origin and destination addresses.
