Convert via percentage: 4.0->% = (gpa/4)*100, 5.0->% = (gpa/5)*100, then %->4.0 = %/100*4

How does this work?

GPA scales differ: 4.0 is standard, 5.0 weighted for AP/IB. Convert via percentage as intermediate: to percent then to target scale.

Letter grades roughly: A 90-100% = 4.0, B 80-89% =3.0, etc. Weighted scales add 1.0 for AP.

For YMYL decisions, verify with authoritative sources (CFPB, IRS, WHO, or a licensed professional) and run conservative vs optimistic scenarios. This tool is educational, not professional advice — it assumes constant inputs and excludes fees, taxes and variability that affect real outcomes.
