X-Cart comes with the US measurement system by default, i.e., inches for dimensions and pounds for weight. However, if your country's measurement system differs from the US, you can set up your store to match your locale and market.
To configure the units of measure and date formats for your store:
Go to the Units and Formats page of your store's Admin area (Store setup > Localization):
Use the settings in this section to adjust the localization parameters for your country:
Weight unit: The main weight unit that should be used in your store to measure the weight of products, shipping boxes, etc. The available options are:
Weight symbol: This field adjusts automatically depending on the weight unit selected above.
Hide trailing zeros in fractional part: This setting specifies whether the trailing zeros in the decimal numbers (typically, weight values) should truncate when such numbers are displayed on the storefront. Note that this setting does not affect the numbers in the Admin area. For example, if you set the weight of a product in the Admin area as "1.5000 lbs" and the setting "Hide trailing zeros in fractional part" is enabled, the same weight will display on the storefront as "1.5 lbs".
Weight format: The format to display weight values on the storefront.
Percent format: The format to display percent values in the storefront.
Dimensional unit: The main dimensional unit that should be used in your store to measure the size of products, shipping boxes, etc. The available options are:
M ( meter(s));
Dimensional symbol: This field adjusts automatically depending on the dimensional unit selected above.
Date format: The format to display dates in the store.
Time format: The format to display time in the store.
Time zone: The time zone to which your store belongs geographically.
CSV column delimiter: The character that delimits columns in your import/export CSV files.
Import/export charset: Define the charset used for your import/export CSV files.
Once you complete the configuration, click Submit at the bottom of the page to save the changes.
