I currently have a GPA of 8.6 on the McMaster 12-point scale.
I'm trying to convert it to the 4-point scale and a Letter-grade.

I only see whole numbers on the GPA Conversion Chart (http://careers.mcmaster.ca/students/...nversion-chart)

Does this mean I round up my GPA to a 9? Or use linear interpolation? (then I'm not sure whether I have a B or B+)

you convert each grade from the 12 point scale to the 4 point scale. Then average it.
Do not take your average on the 12 point scale and convert it into the 4 point scale.

It's a B. They don't round up, at least that's how it's been with my experience.

How do you average GPA (in terms of 4-point scale), with like weighted courses and all that?

The OMSAS conversion table is used to calculate your equivalent GPA on a 4-point scale.
It's like FireDragoonX said; You first convert every final mark you got into the equivalent GPA (max. 4.0), then average those GPA's to calculate your final GPA.
Full courses count fully, semester courses must be weighted 50%.

Do you mean how half-courses are weighted? Or how med schools like Western calculate their weighted cGPA for admission?

So basically... if say I got 3.70 in a 3-credit course, how would you weigh that as 50%? Just divide it or?

I think the easiest way is if you just count the 6-credit course as two. So if you have 3 and 3.3 in 3-credit courses and a 3.7 in a 6-credit courses you do 3+3.3+3.7+3.7 and divide by 4.

The way I do it is I take the 3-credit course at face value and the 6-credit course at double their value, add them all up and then divide by 10 (assuming that you have 30 credits).
Short example: 3-credit courses: 3.0, 3.7, 3.9, 4.0 and 6-credit courses:3.7, 3.7, 3.7
you calculate (3.0+3.7+3.9+4.0) + 2 x (3.7+3.7+3.7) = 36.8 and divide that by 10
So the GPA is 3.68
Edit: I just realized that this is exactly what jhan said...

what about courses that are worth 4 units? or 2 units?

I'm not sure if this is the easiest way, but I couldn't figure it out using ratios because I don't have a handheld calculator and I'm too lazy to figure it out on the computer calculator, but just multiply your grade by the number of credits, add them all up and divide by the total number of credits.

Example:

3.3 - 3credits
3.7 - 4credits
3.0 - 2 credits

Average: (3.3*3+3.7*4+3.0*2)/9

So... (9.9+14.8+6)/9 = (30.7)/9 = 3.41111111111

I think that's right...

No, I don't believe they do.

Kind of a random question...but do you all tell your parents your marks?

I tell my parents my marks... I'm one of the lucky ones because my parents pay for my university. So I feel obliged to show my marks to them.
