Product Weight - changing from pounds (lbs) to kg

2.0.0 and above

Starting in Zen Cart 2.0, the SHIPPING_WEIGHT_UNITS field is added to the configuration table to assist shipping module developers who wish to offer dimensional shipping please see please see Shipping Dimensions for details. :

The screen referenced is:

• Configuration > Shipping

• When you change SHIPPING_WEIGHT_UNITS to kg you will also want to change these language defines inincludes/languages/YOURTEMPLATE/lang.english.php`:

  • TEXT_PRODUCT_WEIGHT_UNIT
  • TEXT_SHIPPING_WEIGHT This way your storefront will show the correct units. See 1.5.8 below for details

Your admin will show the weight units which are indicated by the setting of the constant above, SHIPPING_WEIGHT_UNITS. Except for the orders detail and products attribute preview pages, to change this you need to change the language defines in YOURADMIN/includes/languages/lang.english.php

• TEXT_PRODUCT_WEIGHT_UNIT

The easiest way to do the for zen cart 2.0+ is to create a lang.admin_override.php file in YOURADMIN/includes/languages/english/extra_definitions/ and add the value to the define array. See [UK Customisation - Date to dd/mm/yy, weight to kg, and USD to GBP](/user/localization/uk_language_overide_files/#Admin file changes).
