1g = 1ml = a 1x1x1cm cube if pure h2o

g = weight
mL = volume (3d)
cm = distance (2d)

g isn't the unit of weight, it's the unit of mass, the unit of weight is N(ewton) and depends on the gravity, only the mass of an object is always the same, not the weight. Your weight on sea level is higher than on the Mount Everest. This is one of the biggest fail in the imperial system, there isn't a difference of weight and mass and the cause of even deathly accidents.

Woosh. Yeah, it keeps feeling counterintuïtive to go from mili to centi

[–] n3m37h@sh.itjust.works 2 points 2 days ago (1 children)

Just move the decimal place, how hard is that?

[–] Schlemmy@lemmy.ml 1 points 2 days ago (1 children)

I know.. But from square to cubic

How a 1x1x1cm cube = 1ml of h2o?

[–] Schlemmy@lemmy.ml 1 points 1 day ago

Yeah. I'm over 40 years into the metric system and I keep making this mistake intuitively. I don't make it when doing calculations bit just when quick guessing.
