For things that are "hmmm".
Rule 1: All post titles except for meta posts should be just plain "hmmm" and nothing else, no emotes, no capitalisation, no extending it to "hmmmm" etc.

Not sure what that gobbledygook unit means, probably something like the pressure of some ancient king’s farts, but yeah the pressure is surprisingly low, about 3kPa.
A few years ago the utility company had to replace my gas meter. You’d think they shut off the gas before they take the meter out, but no. They made sure the area was ventilated (i.e. front door was open) and just unscrew the old meter and quickly grab the new meter and screw it in. He just put his hand over the hole while he put away the old meter and grabbed the new one.
The pressure is so low that not a lot of gas escapes in the 10 seconds it takes to replace the meter even when the pipe is fully open.
