If we take the banana to be 180 grams and the square dishwasher to be 0.36 square meter, that would come to about 140,000 bananas per square dishwasher.
For road bicycles 7 bar is just "normal", 8 and above isn't unheard of.
A guy once asked if I was crazy when I was pressurizing my hybrid bike to 6 bar, and I just pointed to the sidewall where the rating said 4.5-6.5 bar. The range is wide because the pressure you should use varies depending on what you weigh, and how you want to balance rolling resistance vs comfort.
And even then the safety margin on bike tires is more than double the max rating, so it's perfectly safe to go a full bar over if you want.
As much as hPa is legitimate, in English speaking contexts I wish we kept to 10^3 prefixes. (Pa, kPa, MPa, GPa etc).
Like how we keep to nm, μm, mm, m, km. Mostly.
Or if one really must, atmospheres. Other units are just more of a pain to convert between, like yeah, it's metric, so it's not THAT hard, but just nicer in my opinion if it's consistent intervals.
Alas, at least I very rarely need to deal with PSI. Only with valve manufacturers using imperial valve coefficients (Cv values), grumble, grumble. They don't even include the units usually, which to me is heresy. The units are US gallons/min of water at 60 °F per pressure drop of 1 PSI. Like, US engineers have this really stupid habit of not including units in constants and coefficients in some contexts, drives me up the wall.
Thanks for being the convenient recipient of this metric engineer's unit rant.
As far as I know hPa is the preferred unit for air pressure and is used a lot. Usually referring to the air pressure of the atmosphere.
Also hectometer is used a lot when talking about land measurements. And we don't mostly keep to mm and m, in my experience cm is the most used and most useful measurement for every day objects.
All of the different prefixes are valid and are used. It just depends on what context, which one is the most useful. No reason to stick to the 10^3 units, just use them all.
If you consider that a car weighs hundreds of kilograms but its contact surface with ground is something like 100 squared centimetres, that pressure makes sense
Once my roommate punctured one of my tires and I went to a gas station and filled it up. Must have been one of my first times doing it ever. As I got back on the highway my car finally showed the pressure, it read 73….
Don't feel bad ... I drove down the road once in my old truck and started feeling a terrible shaking ... I drove for a while hoping it would go away but it got worse. I finally pulled over and had a look at front passenger side tire .... a bulge was sticking out of it like a giant bruise and once the tire stopped moving, the bulge grew ten sizes and as soon as I realized what it was, I turned away and the thing exploded!
