How do I convert my Philippine grades to American standard grades?

I recently migrated last January from the Philippines to the US as a sophomore in high school. In the Philippines, I was a B-average student, while here, I am an A-average student. I have noticed that the grading system in the Philippines and the specific school I went to was much more difficult than the American standard grading system. My current school did not convert my grades which has heavily affected my GPA. I am currently a junior.

How am I able to convert my Philippine grades to American grades? If I am unable to, should I mention that on my college application (I’m pretty sure it’s called a Common App)? Anything will help, thank you! :-)
