Alvin, Simon, and Theodore; but don’t forget Dave Seville.

There are subs that can make that trip, plus, snoozers. :^) Now, if they found a Rolex down there...

20,000 X 3 = 60,000.............

Marianas Trench... Pacific Ocean... Gilligan’s Island... uh, never mind...

Okay, as long as they don’t use any carbon fiber..................

Or the renowned Chinese Cardboardium.

Funny, as a kid, I always thought “20 Thousand Leagues Under the Sea(s)” referred to the depth, which of course makes no sense, since it’s only about 1326 leagues to the center of the earth.

I guess it referred to traveling all over the place while underwater - the plural “Seas” should have given it away. LOL

You know, I noticed that, too.

Sorry.

One source:
a nautical mile is equal to 1.151 statute miles. Or put another way a nautical mile equals 6076.12 feet. So 20,000 leagues = 60,000 nautical miles = 69,060 statute miles.

Another.
20,000 metric leagues (80,000 km, over 40,000 nautical miles), nearly twice the circumference of the Earth.
A league is 4,828.03 meters, approximately 3 miles.

20,000 leagues equal about 60,000 miles as you said.

There’s British and US difference as well................

Cleaning out my Mom’s house three years ago, I found in a folder of an eight page report on Alvin I did in fourth grade in the 60’s. Included was a drawing of Alvin and it’s support ship.

How much is that in leagues?

Leagues are a measure of length, not depth.

The distance varies from 1.4 to 4.9 miles.

So, 20,000 leagues under the sea could be between 28.,000 and 98,000 miles.

I know.

I’ve worked with two ex Alvin pilots. Both remarkable people.
Steve held the hardhat diving record for a while. His brother was Provost at Stanford. (like Condi Rice)

[dljordan]

Nope.

[ProtectOurFreedom]

But how many leagues under the sea?

[cableguymn]

Or video game controllers

[ProtectOurFreedom]

“a measure of length, not depth.”

Hmmm, if we can’t measure depth as length, do we measure is as width?

(for the happy results when this thing implodes around and through you.)

This one wasn’t designed by a DEI engineering team. Straight white men built this baby. It’ll do just fine.

[Red6]

I think the Trieste went down the Marianas trench.

[GingisK]

So, 20,000 leagues under the sea could be between 28.,000 and 98,000 miles.

Surprisingly versatile for a unit of measure.
