| Decimal → Percentage | Multiply the decimal by 100 | Percentage → Decimal | Divide by 100 |

| Number → Percentage | Express number as fraction → Multiply by 100 | Percentage → Number | Divide by 100 → Whole number if denominator = 1 |
Quick conversions for common test marks (Max Marks = 200):
| Marks Obtained | Percentage |
