I agree.

For a normal person it is almost impossible to understand all these
interesting topics when it is full of gallons, feets and psi's instead of
litres, meters and Pascals

I'm sure I'm not the only one who had to look this up, not knowing
what a psi is equivalent to. I'm sure everyone knows that 1 atmosphere
= 101.3 kPA ... but many of us forget that this equals 14.7 psi

So they pressurised to 1.16 atmospheres (117.2 kPa) and then dropped
to 0.24 atm (24.1 kPa).
