Yup, in sciences anyway (including econ), to get your percentage:
Grades 1-5: multiply your grade by 8 (so a 5=40%, 4=32% etc, not that it matters much)
Grades 6-16: going up from 40%, each increase in your mark by 2.5% corresponds to an increase in your grade by 1 (so a 7 is 45%, a 9 is 50%, a 15 is 65%)
Grades 17-20: the formula says take 10 a way from your grade, then multiply that number by 10 to get the % (so a 17=70%, a 18.2 = 82%, a 19.8 = 98%)
The grading system is a bit odd to say the least, especially as they dont explain that although your grade is a number and the max is 20, the grade you get is not "12 marks out of 20" etc.
Also, the correlation of % to grade differs between some subjects, eg a 20 is not always 100%, eg when its something subjective such as an essay, where a marker is more likely to say "the standard of that work is more than enough to comfprtably gain a 1st" and give it an 18.5 for example, rather than tally up marks for it.
The uni should probably explain to its students how their grading system works, rather than lettign them find out for theirselves. Or just change it to something that makes more sense.
