minus-squaretowerful@programming.devlinkfedilinkEnglisharrow-up0·12 days ago Can you calculate the weight of a sphere of 9 m of displaced water ? No ? Well, it is 382 tons. Metric strikes again. I bet you didn’t even have to convert through football fields, elephants, or olympic sized swimming pools!
minus-squareA_A@lemmy.worldlinkfedilinkEnglisharrow-up0·12 days agoindeed i made a very simplified calculation not taking into account increase density of salted water nor increased density because of compressibility of water at 500 m deep. Basically i took 1m³(water) is 1 (metric) ton.
