Thesis as part of graduate GPA?

Hello! I graduated college a few years ago and then did a 2 year masters abroad. Where I did the masters, you don’t “defend” your thesis. Instead, you get a letter grade for it. That one letter grade is weighted the same as a full year of credits. So, my first year of 9 courses was worth 120 credits (classes here are 10+ credits each) and my thesis is worth 120 credits also. I’m fairly sure getting a grade for a thesis isn’t a thing in the US, so will this thesis grade go into my graduate GPA?
