I recently moved to Germany, with kids (teens & pre-teens), where Netflix etc. show movie's ratings with the local rating/certification system. This led to questions from my kids about what they could watch.

I made this page to get a better understanding of how the German ratings map to US ratings. Since I was downloading data from anyways, I just made it able to compare between all the countries I got data for.

There's a Github link at the bottom of the page in case you want to pull your own data or load in data for other countries.
