Canadian University GPA Question

[b39]

Hi Everyone I'm hoping someone can help me with this question as I have been referred to many sources but still can't quite figure this out. 

 

I just finished my undergrad at York (9 pt scale GPA) and I've applied to UofT which as far as I know works on a 4.0 scale.

I received a pretty disappointing grade for a course worth 6 credits today ( B ). I'm trying to figure out how this will affect my overall GPA. 

 

In my final year of study (which comes out to 33 credits because of 6 credit courses) every other course is an A,  (on the 9 point scale, so an 8) except for one 3 credit B+

 

Basically... 

6 credits: B

3 credits: B+

24 credits: A

 

Please someone tell me how I can figure out my GPA in the four pt scale or at least how to convert each grade individually. I'm having a major anxiety attack that this B has ruined my chances of being competitive
