Default language and currency locale are two options that an administrator should configure in the company settings to support a global team of Salesforce users. Default language determines the language that is used for labels, buttons, tabs, help text, and messages in Salesforce for all users unless they override it in their personal settings. Currency locale determines the format of currency fields and numbers in Salesforce for all users unless they override it in their personal settings or enable multiple currencies.
