Whole-box example
A box covers 1.23 m² and costs 600 currency units. A request for 2.46 m² gives 2 boxes / 1,200; 2.47 m² gives 3 boxes / 1,800. Actual supplied area is 3.69 m². Tax and shipping are calculated separately by WooCommerce.

Works with simple products, not variations or bundle formulas. The WP Desk Flexible Quantity plugin is incompatible with measured products in the verified configuration. Test payment, shipping, stock and theme integrations on a staging copy. Installation updates from our website are manual; WordPress.org automatic updates are not available yet.
Already using LIO Product Units 1.1.0? This is a renamed plugin directory, not an in-place WordPress upgrade. First make a staging backup, deactivate the legacy plugin, then install and activate LIOSFERA Product Units. Do not enable both plugins at once. Existing product measurement metadata is reused; do not select the legacy plugin’s delete-on-uninstall data option. The original legacy ZIP remains available.
WordPress.org review: Awaiting Review (1 November 2026). The Plugin Directory accepted the initial LIOSFERA Product Units Free 1.1.0 submission under the provisional slug liosfera-product-units. It has not been reviewed, approved or published. The direct LIOSFERA ZIP remains available; automatic updates from WordPress.org are not available yet.
Free 1.1.0 is a direct publisher release, not a listing in the WordPress.org Plugin Directory. It has been tested on isolated WooCommerce and LIOSFERA QA, but cannot guarantee compatibility with every third-party extension.
