I had never heard of it myself, but looking at the definition instantly reminded me of board feet for measuring lumber, but that makes sense as wood is a solid and has a fixed length, width, and height.
For water, especially water you would be moving, I’d think gallons to some per of ten. Moving up from gallons looks to get into barrels it pipes which are also very not-picturable units.
Looking up how ocean volunteers are displayed, cubic miles or cubic km, still seems unimaginable, as what else do we picture on that scale?
I have the Wembley Stadium unit as a spoof of the banana for scale, but even never having seen that in person, picturing a generic stadium of water feels more relatable than whatever acre-feet or cubic miles are.







I could visualize a commercial 55 gallon drum ok, but a barrel for volume measurements is 42 gallons. I’d never even heard of that before today.
Give me metric already. I’ve worked in pharma related fields for 20 years, all anyone cares about there is metric. I can visualize something I never actually seen like a deciliter easier than I can a “barrel.”
