How are decimal values in CGPA treated during conversion to percentage?

 At SPPU, when converting CGPA to percentage, decimal values are treated according to standard rounding conventions, but the official method is precise—all decimal places in the CGPA are taken into account before multiplying by the conversion factor. Here’s how it works:

---

1. Standard Conversion Formula

$$\text{Percentage} = \text{CGPA} \times 10$$

• If your CGPA has decimals, e.g., 7.36, the percentage is:

$$7.36 \times 10 = 73.6\%$$

• No truncation is done before conversion; the full decimal is used.

2. Rounding Rules

• After conversion, the percentage is usually rounded to two decimal places for mark sheets or transcripts.

  • Example: 73.678% → 73.68%

• Some transcripts may round to the nearest whole number (73.68% → 74%), depending on formatting policy.

3. Effect on Classification

• Even small decimal differences can affect degree classification:

  • First Class (6.50–7.49 CGPA → 65–74.9%)

  • Distinction (≥7.50 CGPA → ≥75%)

• So precise decimals are important for accurate representation.

✅ Key Point: Always use the full CGPA value from the transcript when calculating percentages. Avoid rounding early, as it can slightly change the result.
