JL Johnson :veri_mast:This old house has a humidity problem which became quite evident when we had an episode of “crying walls.” 😱
So I’ve been eyeing a dehumidifier for a while, and Costco got me. The thing pulled a gallon of water out of our air in 8 hours. That seems like a lot?

️@User47@vmst.io I stayed in a Ketchikan Airbnb that had a dehumidifier with a sign on it saying "Do not turn off." It was off because the bucket was full. I emptied the bucket and turned it back on. Even though I shut it off at night (so I could sleep) it was still full before I left.
JL Johnson :veri_mast:I understand relative and absolute humidity but never had a need to understand what that means in actual volumes.
Guess that’ll be my procrastination project this morning.
JL Johnson :veri_mast:First observation: The default math is all metric. Except for temps. I’m all-in for metric w/ most things (not speed, or ambient temps) but I guess in order to do this exercise I need to get comfortable w/ square and cubic meters. I’m cool w/ meters but my intuitive anchor struggles to accept them squared or cubed. So this’ll be fun.
Aaron Sawdey, Ph.D.@User47@vmst.io I always find looking at the dew point to be a good way to understand the humidity level, it makes it independent of temperature. And it’s very similar to absolute humidity but generally much easier to find/calculate. A gallon in 8 hours is quite a bit but not unprecedented. Just means you got a decent dehumidifier, and it’s damp in your house.
JL Johnson :veri_mast:@acsawdey@fosstodon.org it was consistently mid/high 50s, peaked at 62 which was just disgusting. Ambient temps. ~71-78
simonbp@User47@vmst.io A cubic meter of water is one metric tonne, 1000 kg. One litre of water is one kilogram. It does make it easier when you're literally working with water.
JL Johnson :veri_mast:@simonbp@social.linux.pizza I remember being blown away as a kid to learn 1 ml of water weighs a gram. Never had a reason to extrapolate that to tons. So cool. metric rocks!
