# How to calculate GPA on a 4.0 scale?

Registered User Posts: 318 Member
edited July 2009
Hi, I'm from Canada, and we talk about marks on the 100 scale, so I don't really understand how to convert it to the American GPA scale. Does 4.0 mean a 100 average? and what's the difference between Weighted and UW and how do you calculate both?

Also, is it for all 4 years of high school or just 11 and 12 or what?

A formula i use is:
(number on scale of 1-100) X(variable)
_____________________ X _________________
100 4.0

So for example:
86 x
___ X ____
100 4
=
344=100x
344/100=3.44
x= 3.44

Weighted is with added honors/ap classes as extra points
and typically
a: 4
b: 3
c: 2
d: 1
f: o

Thanks.

What's considered an A in the US? because here in Canada it's from 80% to 100%, but I keep hearing that A is 90-100 in US.

Also, is the GPA for all 4 years of high school or just 11 and 12 or what?

GPA in the US is for all 4 years of high school. Some schools do A 90-100, some do 93-100, and others do 94-100. Then some schools are retarded like mine and do 96-100=4.0.
One of the things about GPA is that you don't convert from numerical average to the 4.0 scale. You may have an A average (Like a 93) but have gotten a few B's. You would not have a 4.0.

The best way I can tell you to calculate is this:

(4*(# of A's)+3*(# of B's)+2*(# of C's)+1*(# of D's)+0*(# of F's))/(# of classes attempted)

If your school doesn't calculate a GPA it won't matter so much although you'll be hurt if your school doesn't rank. Some US schools are sympathetic to Canadians and their grading scales and others aren't. Frankly this would all be easier if schools came up with whatever grading scales they like and simply report letter grades with pluses and minuses.

all the way above is just the standard way...
but sometimes there's little difference...

My school is on a 12.0 scale. how would I calculate mine?

Thank you very much. Wow, so it counts from Gr9 to 12... My grade 9 and 10 marks are going to bring down my GPA then... :(

How do I add points if I took enriched courses?
