1 ri = 0.392727 km.
So 20,000 miles is about 7,855 km.

To be exact, 1 ri = 0.392727 km, but usually 10 ri is 4 km.
So it's about 8,000 kilometers.

It's about 8000km.
Come to think of it, I didn't know before, but about 8,000 kilometers under the sea is close to the maximum depth that a real submarine can enter.
