Changing content language in wordpress

Hi All,

Hope i can get some help from the team on here. i have a blog website on wordpress which all my content is in french, is it possible to get all the content that shows in the dashboard to display in english and for that change to reflect what visitors see without using any browser plugin to do the translation.

i know if i go to to my site using google chrome it pops the option to translate the content to english but i am looking for a way which doesn't require the browsers to translate and for everything to be done in the backend.

Thanks
Abz
