So in Naruto, shinobis are extremely powerful, to the point that a single genin is 10 times stronger than the average person. So here is how the cultivation levels compare to the power level of the Narutoverse in terms of physical prowess. A shinobi's strength may vary due to bloodline limit and jutsus.
Each cultivation realm is separated by 9 levels. But there is a 'level 10' however it's just called the "Peak Level".
Human Realm:
Level 1-3, Genin.
Level 4-6, Chunin.
Level 7-9, Jounin.
Peak Level, Kage.
Demigod Realm:
Level 1-3, Peak-Level Kage, Sage Mode Naruto, or MS Sasuke.
Level 4-6, Bee(Hachibi Mode), Third Raikage and Pain.
Level 7-9, Hiruzen, Tobirama, and EMS Sasuke.
Peak Level, Hashirama and Madara.
Transcendent Realm:
Level 1-3, Semi-Juubi Obito, and Synchronized Naruto and Kyuubi.
