To calculate your JEE Main percentile from the score of 5.4759270, it’s essential to consider factors like the total number of candidates, difficulty level of the exam, and your score in relation to others. The percentile is a ranking that represents the percentage of candidates who scored lower than you. Generally, a score of 5.4 would likely result in a lower percentile, possibly in the range of 30-40 percentile, but this varies each year. For a more accurate estimate, you can refer to official JEE Main results.

The percentile in JEE Main is not a fixed conversion from your raw score. Instead, it's based on how your score compares to the scores of all the other students who appeared in the same session as you. The National Testing Agency (NTA) calculates the percentile by looking at the number of candidates who scored equal to or less than your score.

With a score of around 5, it's highly likely that a very large percentage of students would have scored much higher than you. This would place you at a very low percentile.

To give you a rough idea:

• A score around 0 often results in a very low percentile, typically in the single digits.
• Higher scores are needed to get into even the lower percentile ranges. For example, to get a percentile above 50, you would need to score significantly more than 5.

Therefore, with a score of approximately 5.47, your percentile is expected to be quite low, likely in the single digits or very low teens at best. It would mean that a very high percentage of test-takers scored better than you.

Keep in mind that the official percentile will be released by the NTA after the results are compiled for all sessions of JEE Main. You will need to check your official scorecard on the NTA website to know your actual percentile.

I hope this helps.
