Formula

Based on the Grade Point Average to Percentages given in the Faculty of Science and Engineering Calendar in 2011, we use polynomial regression in Excel to get the following equation:

f(x) = 0.0076*(x**5)-0.1541*(x**4)+1.154*(x**3)-3.9327*(x**2)+11.017*(x)+38.958

Python

Here’s a quick and easy way to implement this in Python 3:

def yorku_percent(cpga):
    """
    Calculates grade percentage from CGPA based on Faculty of Science and Engineering Calendar.
    """
    if cpga < 0 or cpga > 9:
        print("Invalid GPA")
    else:
        percent = 0.0076*(cpga**5)-0.1541*(cpga**4)+1.154*(cpga**3)-3.9327*(cpga**2)+11.017*(cpga)+38.958
        print("A cumulative GPA of " + str(cpga) + " is approximately " + str(int(percent)) + "%.")
