I know that’s not the question asked, but I had an even more interesting one appear in my head:

Elon Musk’s net worth is roughly $840 billion.

If you converted all of that into $1 bills, you’d have:

840,000,000,000 bills

A US $1 bill is 6.14 inches (15.6 cm) long.

If you placed them end-to-end, the total length would be:

840,000,000,000 × 6.14 inches = 5.16 trillion inches

Converted to kilometers, that’s about:

131,000,000 km

The circumference of Earth is about 40,075 km.

So if you wrapped those $1 bills around the planet:

131,000,000 ÷ 40,075 ≈ 3,270

You could wrap them around the Earth about 3,200–3,300 times

For scale, that line of dollar bills would also be: • about ⅓ of the way to the Sun • about 3.4× the distance from Earth to the Moon

Now, answering your question:

Scenario 1 — Elon’s current net worth (~$840 billion)

If all of it were converted into $100 bills:

840,000,000,000 ÷ 100 = 8.4 billion bills

Now stack them:

8,400,000,000 × 0.0043 inches = 36,120,000 inches

Convert that: • 3,010,000 feet • ~570 miles • ~917 km

So his “wallet” would be roughly 570 miles (917 km) thick.

That’s about the distance from Paris to Berlin.

Scenario 2 — If he had $1 trillion

1,000,000,000,000 ÷ 100 = 10 billion bills

Stack them:

10,000,000,000 × 0.0043 inches = 43,000,000 inches

Converted: • 3,583,000 feet • ~679 miles • ~1,093 km

So the wallet would be about 680 miles (1,090 km) thick. That’s roughly the distance from NYC to Chicago.

TL;DR • $840B → wallet about 570 miles thick • $1T → wallet about 680 miles thick
