JEE Mains is a National Level Exam and AO EAMCET is a State Level Exam. If we calculate your rank with your percentile, it is approximately 56485. The formula is 100-your percentile*no.of candidates who wrote the exam/100.  This is your All India Rank. This cannot be converted to AP EAMCET rank. But if you manage to do the same way in AP EAMCET also you can score around 18000-20000 State rank.
