Hello there,
How to translate weight symbols or add a new one?
Thank you!

Hi,

You can go in the Languages tab of the HikaShop configuration, edit your language file, and in the translation override area, you can add a line to translate the symbol.
Like this:
KG="My translation"

Thank you, Nicolas!
Works great!
