pressure on submersible was equivalent to the weight of 2 SUVs on a postage stamp

Categories: Comparisons

An example of a comparison with an everyday referent to offer scale:

"You mentioned the pressure, what was it 4930 psi?* If we put that in the context that you might better understand it, it's like having 2 SUVs, the weight of 2 SUVs, standing on an area the size of a postage stamp."

Jonathan Amos (science correspondent) talking to the item 'final report into Titan sub implosion released' on BBC News channel (15.05, 5th August 2025).
