Why there is no single percentage to GPA formula
Each country, and often each university, publishes its own table. One shortcut you will see online divides by 100 and multiplies by 4, which turns 80% into 3.2. None of the tables here works that way. On the 10-point scale, 80% is a B, worth 3.0. On the plus/minus scale it is a B-, worth 2.70. HEC's table in Pakistan makes it an A-, worth 3.34 to 3.66 grade points.
So convert on your own school's table. Most tables turn the percentage into a grade first, and the grade sets the points.

The 10-point scale is the one Florida law sets for public school grades 6 to 12. The plus/minus scale is the Johns Hopkins School of Nursing's. The US has no national scale, so check your own school's. The Grading Scale page lets you set and print your own.

Converting a GPA back to a percentage
A grade covers a range of percentages, so a GPA rarely turns back into one exact percentage. Some systems publish a rule for it. GradeCat has calculators for HEC's CGPA to percentage in Pakistan, CGPA to percentage in India and CGPA to percentage in Bangladesh.
Systems not in the converter yet
Singapore, Hong Kong and Kenya have GradeCat pages but are not here. GradeCat has confirmed the marks for only the top Singapore Polytechnic grades. Its Hong Kong scale has letter grades and points but no percentages. And KNEC sets each KCSE subject's grade boundaries without printing them in its regulations. A system is added only once its table is confirmed.
