The top grade at UoK is A+, awarded at 85% and above. Grading here is absolute. It is published early and holds. With this many tiers, the difference between two adjacent letters is small enough that rounding matters. The university sits in Kelaniya and dates to 1959.
12 grades sit on the scale. D is the last grade worth anything, at 1 point, and it starts at 25 to 29.99%.
There is no published percentage mapping. Ask the examination office before you write a figure on a form that carries a signature.
Rules move from one intake to the next. If your transcript disagrees with the 12-grade table above, your transcript wins, and we would rather re-read the source than argue with it.

Take each grade point, multiply by that course's credits, add them up, divide by the credits you attempted. That weighting is why a heavy course pulls harder at UoK than a light one.
Only when UoK or the receiving authority publishes an accepted conversion for the purpose at hand. Otherwise you are converting a verifiable figure into an unverifiable one.
