Percentage to SGPA Converter

Reverse an SPPU percentage into an SGPA using both the standard rule and the Circular 332 bands.

Percentage to SGPA Converter

Your SPPU percentage

Both the standard SPPU rule and the Circular 332 band equations are reversed, because the two give different values for the same percentage.

%

Percentage is required.

Result

Standard rule first, Circular 332 band second.

About this tool

SPPU publishes two conversions, a standard 0.75 deduction and the grade banded equations of Circular 332 of 2020. This converter reverses both so you can see the SGPA under each, since the same percentage produces different grade points depending on which rule the certificate used.

How it works

Using the Percentage to SGPA Converter in three steps

Every step below reflects the actual calculation this tool runs, so you can check the result by hand if you need to.

  1. 1

    Enter the SPPU percentage from your marksheet or equivalence certificate.

  2. 2

    The tool applies the standard reverse rule, adding back the 0.75 grade points.

  3. 3

    It also identifies which Circular 332 grade band the percentage falls in and solves that band equation, so you can compare both values.

Reverse SPPU conversions

Standard: SGPA = (Percentage / 10) + 0.75 | Circular 332: inverse of the band equation
  • The Circular 332 table applies a different equation to each grade band from O down to C.
  • The tool finds which band the percentage lands in, then solves that band equation numerically.
  • Where the university issued a certified percentage, use the Circular 332 value.

Frequently asked questions

Which of the two values should I quote?

Use the Circular 332 value when the percentage came from a university issued equivalence certificate, and the standard value for quick estimates.

Why do the two answers differ?

Circular 332 fits a separate straight line to each grade band rather than one rule for the whole scale, so the two methods diverge away from the middle of the range.

What if my percentage falls outside the table?

Percentages below the C band are not covered by Circular 332, so only the standard reverse rule is shown for them.

Which grade bands does Circular 332 cover?

The circular publishes separate equations for the O, A plus, A, B plus, B and C bands, each fitted to its own CGPA range.

Why does the standard rule sometimes read higher?

The banded equations have steeper slopes at the top of the scale, so at high percentages the two methods pull apart by a few tenths of a grade point.
