minus-square@S_H_K@lemmy.dbzer0.comlinkfedilink4•13 days agoTake one liter of water at “room temperature” an aprox of 20 Celcuis degrees at one atmosfere pressure. Take a straight transparent tube of one centimeter inner thickness. Put the water in without spilling. Measue… A meter…
minus-square@groet@feddit.orglinkfedilink2•13 days agoThat’s wrong. The tube has a cross section of 0.25π cm² so your tube will be filled ~1,2732m high. Also as others have stated, if you can measure 1cm you already have a definition of a Meter.
minus-square@kureta@lemmy.mllinkfedilink1•13 days agohow am I supposed to measure the inner thickness?
