What does 20000 leagues under the sea mean?
"20,000 Leagues Under the Sea" refers to the immense distance traveled by Captain Nemo's submarine, the Nautilus, throughout the story, not the depth it descended. A league typically represents about three nautical miles. Therefore, 20,000 leagues equates to approximately 60,000 nautical miles, or about 69,000 statute miles, covering a vast journey across the world's oceans.
