How to get an official GPA conversion

To whom it may concern,
I am an EU student interested in applying for the M.Sc. in Ocean and Climate Physics. Regarding the transcript of records requirement, my home university does not provide an official GPA conversion from our 10-point scale. Could anyone please advise me which institutions or official services are recognized for doing this conversion? Thank you for your time
