You don't need to know the typical pressure , but you definitely get the idea the pressure built inside a steam engine is much higher than atm.
The steam pressure is not about the numbers so much but a kind of hyperbole , "you know that thing which hauls tonnes of steel purely on pressure made in a steam boiler , yeah the pressure on Venus is 4 times that pressure "
I found it an interesting fact.

I didn’t think of it that way initially, but this makes sense, thanks.

Why reference submarines? What submarines can reach is irrelevant as a comparison when you know a number
Otherwise, it's your reference to submarines that contextualizes the number, same as the insides of a steam engine does for others

I realised that after the fact. What I meant to say is that standard units should be used, and individuals should be left to contextualise said units of their own accord, instead of it being done for them.
I can also guess what ninety atmospheres entails in terms of engineering, because I know that's the pressure at about 900 m water depth (by virtue of the SI units, which are based off water: P = hρg), which few submarines can even reach.
The same thing goes for 'as long as/as big as xxx football fields': which one? American or association? I know what a square metre is, I know what a square kilometre is, just use the damn units.
I really think pop-sci and science education should emphasise standard units (read: SI, not USC) and being able to estimate orders of magnitude.
There's a pedantic comment below (I saw it coming a kilometre away), but why not make life simple and just say 'about 90 atmospheres'?
