Question 1

How do I convert Nigeria's grades to another system?

Accepted Answer

The conversion uses the published guide "5.0 CGPA to percentage (guide)": Percentage ≈ CGPA × 20. It is an estimate for planning, not an official equivalence.

Question 2

Are these conversions official?

Accepted Answer

No. Conversions between grading systems are estimates. Where an official evaluator exists we link to it, but the receiving institution makes the final decision.

Question 3

Why do different institutions convert the same grade differently?

Accepted Answer

Each institution sets its own equivalence policy, so the same grade can map to slightly different values. Use the conversion as a guide and confirm with the institution.

Question 4

Can I convert the other way, from percentage to the local scale?

Accepted Answer

Where a reverse rule is published we show it alongside the forward rule. Otherwise the conversion is one-directional and we say so on the page.
